Creating Your Own PHP Helpers in a Laravel Project
Laravel provides many excellent helper functions that are convenient for doing things like working with arrays, file paths, strings, and routes, among other things like the beloved dd() function.
You can also define your own set of helper functions for your Laravel applications and PHP packages, by using Composer to import them automatically.
If you are new to Laravel or PHP, let’s walk through how you might go about creating your own helper functions that automatically get loaded by Laravel.
Creating a Helpers file in a Laravel App
The first scenario you might want to include your helper functions is within the context of a Laravel application. Depending on your preference, you can organize the location of your helper file(s) however you want, however, here are a few suggested locations:
*
app/helpers.php
*
app/Http/helpers.php
I prefer to keep mine in app/helpers.php in the root of the application namespace.
Autoloading
To use your PHP helper functions, you need to load them into your program at runtime. In the early days of my career, it wasn’t uncommon to see this kind of code at the top of a file:
require_once ROOT . '/helpers.php';
PHP functions cannot be autoloaded. However, we have a much better solution through Composer than using require or require_once.
If you create a new Laravel project, you will see an autoload and autoload-dev keys in the composer.json file:
"autoload": {
"classmap": [
"database/seeds",
"database/factories"
],
"psr-4": {
"App\\": "app/"
}
},
"autoload-dev": {
"psr-4": {
"Tests\\": "tests/"
}
},
If you want to add a helpers file, composer has a files key (which is an array of file paths) that you can define inside of autoload:
"autoload": {
"files": [
"app/helpers.php"
],
"classmap": [
"database/seeds",
"database/factories"
],
"psr-4": {
"App\\": "app/"
}
},
Once you add a new path to the files array, you need to dump the autoloader:
composer dump-autoload
Now on every request the helpers.php file will be loaded automatically because Laravel requires Composer’s autoloader in public/index.php:
require __DIR__.'/../vendor/autoload.php';
Defining Functions
Defining functions in your helpers class is the easy part, although, there are a few caveats. All of the Laravel helper files are wrapped in a check to avoid function definition collisions:
if (! function_exists('env')) {
function env($key, $default = null) {
// ...
}
}
This can get tricky, because you can run into situations where you are using a function definition that you did not expect based on which one was defined first.
I prefer to use function_exists checks in my application helpers, but if you are defining helpers within the context of your application, you could forgo the function_exists check.
By skipping the check, you’d see collisions any time your helpers are redefining functions, which could be useful.
In practice, collisions don’t tend to happen as often as you’d think, and you should make sure you’re defining function names that aren’t overly generic. You can also prefix your function names to make them less likely to collide with other dependencies.
Helper Example
I like the Rails path and URL helpers that you get for free when defining a resourceful route. For example, a photos resource route would expose route helpers like new_photo_path, edit_photo_path`, etc.
When I use resource routing in Laravel, I like to add a few helper functions that make defining routes in my templates easier. In my implementation, I like to have a URL helper function that I can pass an Eloquent model and get a resource route back using conventions that I define, such as:
create_route($model);
edit_route($model);
show_route($model);
destroy_route($model);
Here’s how you might define a show_route in your app/helpers.php file (the others would look similar):
if (! function_exists('show_route')) {
function show_route($model, $resource = null)
{
$resource = $resource ?? plural_from_model($model);
return route("{$resource}.show", $model);
}
}
if (! function_exists('plural_from_model')) {
function plural_from_model($model)
{
$plural = Str::plural(class_basename($model));
return Str::kebab($plural);
}
}
The plural_from_model() function is just some reusable code that the helper route functions use to predict the route resource name based on a naming convention that I prefer, which is a kebab-case plural of a model.
For example, here’s an example of the resource name derived from the model:
$model = new App\LineItem;
plural_from_model($model);
// => line-items
plural_from_model(new App\User);
// => users
Using this convention you’d define the resource route like so in routes/web.php:
Route::resource('line-items', 'LineItemsController');
Route::resource('users', 'UsersController');
And then in your blade templates, you could do the following:
{{ $lineItem->name }}
Which would produce something like the following HTML:
Line Item #1
Packages
Your Composer packages can also use a helpers file for any helper functions you want to make available to projects consuming your package.
You will take the same approach in the package’s composer.json file, defining a files key with an array of your helper files.
It’s imperative that you add function_exists() checks around your helper functions so that projects using your code don’t break due to naming collisions.
You should choose proper function names that are unique to your package, and consider using a short prefix if you are afraid your function name is too generic.

There are two solutions for one board, using different chips. But one of their i2c address is the same. How to resolve conflict in one dts?
i2cdetect -r -y 10

Hardware can't modify the address. If two dts are used, there will be two firmwares, which is inconvenient.

Positioning agent randomly within GIS space
Each 'Person' has a parameter 'region' which into which I map the value of the 'region' column in my table to. I then need to find some way to set the position of the agent to a random point inside the assigned region.
I have tried:
GISRegion myRegion = main.map.searchFirstRegion(region);
Point pt = myRegion.randomPointInside();
setXYZ( pt.x, pt.y, pt.z );
in the "On startup" field for my Person Agent but it seems that main.map.searchFirstRegion(region); does not do a good job of getting the correct region, as agents are distributed in places where there is no region (i.e in the sea):
Image
Ideally, I would like to use void setLocation(region) but setLocation takes in a Point or INode variable whereas the 'region' parameter is a string. Is there a way to search the list of regions by name for the matching region and return that region?
Thanks!

python valueerror : too many values to unpack
def main():
print ( " This program computes the average of two exam scores . ")
score1,score2 = input ("Enter two scores separated by a comma:")
average = (score1 + score2)/2.0
print ("The average of the score is : " , average )
when I summon the main() I got this ValueError :
ValueError: too many values to unpack (expected 2)
what is wrong with this code ?

Suppress default message of assert_eq! when custom message provided?
Here I'm comparing some very long strs. So it is preferable not to clutter up the console but instead take a limited slice of each.
let left = tds.get_bulk_post_str();
let error_msg = format!("Bulk text is not what is expected: get_bulk_post_str() starts\n{}...\n\nExpected text starts\n{}...\n",
&left[0..20], &expected_bulk_text[0..20]);
// assert_eq! not used because assert_eq! apparently does not suppress its default message even when you supply a custom message!
// ... and in this case the default message is far too long.
// assert_eq!(left, expected_bulk_text, "{}", error_msg);
// instead, I think I'm forced to do something like this:
if left != expected_bulk_text {
panic!("{}", error_msg)
}
... is there any way of suppressing the default message?
If not, this seems a strange design choice, unlike any other language I know. Is it deliberate?
PS I'm aware the first 20 chars of each string might be identical. Obviously if I really wanted to go to town on this I'd have to examine both strings to find out the first case of difference, and just print corresponding slices from the middle.
Bidimensional splines, strictly increasing in one argument
I want to use bidimensional splines but I don't know how to do (how to impose the monotonicity constraint in 2D).
So far, my method is to select several values of Y, and for each values of Y, I compute a monotone splines with respect to X. And then I interpolate to create the whole function q. But I wonder if it was possible to do all this in 1 step?
firebase_storage/object-not-found. No object exists at the desired reference
This is my code.

void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Wallpaper App',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: WallpaperScreen(),
);
}
}
class WallpaperScreen extends StatefulWidget {
@override
_WallpaperScreenState createState() => _WallpaperScreenState();
}
class _WallpaperScreenState extends State {
List imageUrls = []; // Store fetched image URLs
@override
void initState() {
super.initState();
fetchImages();
}
Future fetchImages() async {
try {
final storageRef = FirebaseStorage.instance.ref();
final result = await storageRef.listAll();
for (var item in result.items) {
try {
final url = await item.getDownloadURL();
setState(() {
imageUrls.add(url);
});
} catch (error) {
print("Error fetching URL");
}
}
} catch (e) {
print("Error fetching images: $e");
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Wallpapers'),
),
body: GridView.builder(
itemCount: imageUrls.length,
gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 2,
crossAxisSpacing: 4.0,
mainAxisSpacing: 4.0,
),
itemBuilder: (BuildContext context, int index) {
return Image.network(
imageUrls[index], // Load image from URL
fit: BoxFit.cover,
);
},
),
);
}
}
Use Font Awesome icon as CSS content

I know I cannot use HTML code in content, so is it only images left?

* Have tried multiple combinations of the security chain as suggested on several similar threads
* Added a few more log statements in security configuration code to capture these events and help understand how the new flow works
* DEBUG level log statements added inside the RestAuthenticationProvider.authenticate() are not showing up in the logs, indicating it is not getting invoked, and the flow is breaking before reaching that point.
However I suspect that the configured AuthenticationProvider (tried using authenticationProvider(..) earlier, but that did not work either) and AuthenticationManager are not getting plugged in the chain for some reason. Need help from the community in guiding me to set this up correctly. Thank you.
Implementing an equation involving integrals as a filter
So our lecturer read out his notes/paper and said the equation
could be implemented as a filter.
At first, it seemed difficult to follow the idea but when realizing that integration is same as finding areas under the curve which seems similar to applying a low pass filter so that only the portion of the signal under the threshold is allowed to pass through, it made a bit of sense. But how - meaning to say which function - can I use to implement the above equation? Do I need three filters or can I use just one? How do I use the terms preceding the integrals in the filter?
Thanks in advance

How to I add the sum of 2 dice throw continuously in JS?
Also, how do i get the program to understand that it's game over when the dices shows the "knockout" number?
let knockoutSiffra = 0;
const dices = document.querySelectorAll('.dice');
console.log(dices);
dices.forEach(bt =>{
bt.addEventListener('click', (e) =>{
knockoutSiffra = e.target.innerHTML;
console.log(knockoutSiffra)
})
})
document.getElementById('go')
.addEventListener('click', () => {
if(knockoutSiffra != 0){
choose.style.display = 'none'
play.style.display = 'block'
console.log('kör')
}
else{
console.log('välj ett nummer')
}
const showNumber = document.getElementById('showNumber');
showNumber.innerText = 'Ditt valda nummer är:' + " " + knockoutSiffra
})
// Slide 3
let lost = document.querySelector('.lost')
lost.style.display = 'none';
const dice1 = document.querySelector('.dice1');
const dice2 = document.querySelector('.dice2');
const result = document.querySelector('.dice-result');
const game = document.querySelector('.game');
let score = 0;
game.addEventListener('click', () => {
let d1 = GetRandomDice ();
let d2 = GetRandomDice ();
dice1.src = `Dice img/Dice-${d1}.png`;
dice2.src = `Dice img/Dice-${d2}.png`;
let sum = d1 + d2;
result.innerText = 'Antal poäng:' + " " + sum;
function GetRandomDice(){
return Math.ceil(Math.random() * 6);
}
})
This is just the last part of the HTML

Tried very much of different stuff but i can't get the code to work properly.
PHP compare two arrays and output all with zero at different record
Array1:
ID: 1
ID: 2
ID: 3
ID: 4
ID: 5
Array2, with num value:
ID: 2, NUM: 200
ID: 4, NUM: 400
I want the output like: (adding zero if no record in array2)
ID: 1, NUM: 0
ID: 2, NUM: 200
ID: 3, NUM: 0
ID: 4, NUM: 400
ID: 5, NUM: 0
I am new to PHP, tried array_diff and array_intersect but not find the clue, could you please let me know how can I do that?
Thanks.
Using UPDATE ... SET arr[idx] = ... to aggregate rows into arrays
CREATE TABLE Measures(
expId SERIAL,
iteration INT NOT NULL,
value float4 NOT NULL,
PRIMARY KEY(expId, iteration)
);
So, a table of various measurements, repeated for n iterations.
Though, because we have more data than originally expected, I want to move to a new table layout that instead uses an array column, which overall gives better performance (already tested and benchmarked):
CREATE TABLE TmpMeasures(
expId SERIAL PRIMARY KEY,
values float4[] NOT NULL
);
My problem now is how to get the old data into the new format.
In the simplest case, the data may look something like this:
INSERT INTO Measures (expId, iteration, value)
VALUES
(1, 1, 1.1),
(1, 2, 2.1),
(1, 3, 3.1),
(2, 1, 1.2),
(3, 1, 1.3);
And conversion could be done with a two step process, roughly like this, to first create the array for an experiment, and then populate the iteration values:
INSERT INTO TmpMeasures(expId, values)
SELECT expId, '{}'::float4[]
FROM Measures
ON CONFLICT DO NOTHING;
UPDATE TmpMeasures tm
SET values[iteration] = m.value
FROM Measures m WHERE tm.expId = m.expId;
Though, my problem now is that the UPDATE actually only ever seems to take the first iteration, i.e., iteration = 1.
I am not quite understanding why that is the case.
I suspect, alternative approaches to values[iteration] would try to group by expId, and order by iteration and aggregate that into an array.
Unfortunately, the data isn't perfect, but iterations should line up.
So, the following seems to work, but it's extremely slow, and I don't quite understand why it's needed in the first place.
DO
$do$
BEGIN
FOR i IN 1..(SELECT max(iteration) FROM Measures m) LOOP
UPDATE TmpMeasures tm
SET values[i] = m.value
FROM Measures m
WHERE
tm.expId = m.expId AND
m.iteration=i;
END LOOP;
END
$do$;
Why does the "normal" update statement not suffice?

How to Create a New Table from JSONB_ARRAY_ELEMENTS and JSONB_OBJECT_KEYS in Postgresql?
It seems like there should be an easy way to create a new table from the keys and values.
Here is the request:
WITH sport_markets_api AS (
SELECT ((CONTENT::jsonb ->> 'data')::jsonb ->> 'sportMarkets')::jsonb AS details
FROM http_post(
'
https://api.thegraph.com/subgraphs/name/',
'application/json'))
I tried:
SELECT
jsonb_array_elements(details) ->> jsonb_object_keys(jsonb_array_elements(details))
FROM sport_markets_api
and was expecting a table with columns based on the keys.
Is there a way to set Horizon's timeout on a job class ?
I'm refactoring a class that records a (predefined length of) an audio stream using Symfony process and an OS executable file.
The way it used to work was the job was sent on a regular redis queue, and timeout would be set on the symfony process, effectively making the job run for the time it needed.
Now we want to send the job on a Horizon queue. The timeout is still set on the process, but Horizon's config has its own timeout value in the config. The problem is that the length of the recording will vary from case to case, with an average being 60 minutes, but we do have cases doing for multiple hours.
I could set it up to a very (very) long timeout, but I find it counterintuitive. Isn't there a way that I could specify the value for timeout on a job ? Otherwise, is setting a humongously long timeout the only logical way to do this ? submitted by /u/CouldHaveBeenAPun

I wanted to label the rows so that it groups the same display ID that are right next to each other but would not group them if there's something else in btw.
The desired outcome should be the following:
websit_id
updated_at
display_id
group_label
1222
