Laravel Cheat Sheet is a cheat sheet for making web applications with the Laravel structure utilizing the PHP language. Laravel is a free, open-source PHP web structure, made by Taylor Otwell and planned for the advancement of web applications following the model–see regulator (MVC) compositional example and dependent on Symfony. The greater part of the synopses and models depend on the authority documentation.

Laravel DB Cheat Sheet
Basic Database Usage
DB::connection('connection_name');Running A Select Query
$results = DB::select('select * from users where id = ?', [1]);
$results = DB::select('select * from users where id = :id', ['id' => 1]);Running A General Statement
DB::statement('drop table users');Listening For Query Events
DB::listen(function($sql, $bindings, $time){ code_here; });Database Transactions
DB::transaction(function()
{
DB::table('users')->update(['votes' => 1]);
DB::table('posts')->delete();
});
DB::beginTransaction();
DB::rollback();
DB::commit();
Laravel Query Builder
Retrieving All Rows From A Table
DB::table('name')->get();Chunking Results From A Table
DB::table('users')->chunk(100, function($users) {
foreach ($users as $user) { //}
});Retrieving A Single Row From A Table
$user = DB::table('users')->where('name', 'John')->first();
DB::table('name')->first();Retrieving A Single Column From A Row
$name = DB::table('users')->where('name', 'John')->pluck('name');
DB::table('name')->pluck('column');Retrieving A List Of Column Values
$roles = DB::table('roles')->lists('title');
$roles = DB::table('roles')->lists('title', 'name');Specifying A Select Clause
$users = DB::table('users')->select('name', 'email')->get();
$users = DB::table('users')->distinct()->get();
$users = DB::table('users')->select('name as user_name')->get();Adding A Select Clause To An Existing Query
$query = DB::table('users')->select('name');
$users = $query->addSelect('age')->get();Using Where Operators
$users = DB::table('users')->where('votes', '>', 100)->get();
$users = DB::table('users')
->where('votes', '>', 100)
->orWhere('name', 'John')
->get();
$users = DB::table('users')
->whereBetween('votes', [1, 100])->get();
$users = DB::table('users')
->whereNotBetween('votes', [1, 100])->get();
$users = DB::table('users')
->whereIn('id', [1, 2, 3])->get();
$users = DB::table('users')
->whereNotIn('id', [1, 2, 3])->get();
$users = DB::table('users')
->whereNull('updated_at')->get();
DB::table('name')->whereNotNull('column')->get();Dynamic Where Clauses
$admin = DB::table('users')->whereId(1)->first();
$john = DB::table('users')
->whereIdAndEmail(2, 'john@doe.com')
->first();
$jane = DB::table('users')
->whereNameOrAge('Jane', 22)
->first();Order By, Group By, And Having
$users = DB::table('users')
->orderBy('name', 'desc')
->groupBy('count')
->having('count', '>', 100)
->get();
DB::table('name')->orderBy('column')->get();
DB::table('name')->orderBy('column','desc')->get();
DB::table('name')->having('count', '>', 100)->get();Offset & Limit
$users = DB::table('users')->skip(10)->take(5)->get();Laravel Joins
Basic Join Statement
DB::table('users')
->join('contacts', 'users.id', '=', 'contacts.user_id')
->join('orders', 'users.id', '=', 'orders.user_id')
->select('users.id', 'contacts.phone', 'orders.price')
->get();Left Join Statement
DB::table('users')
->leftJoin('posts', 'users.id', '=', 'posts.user_id')
->get();select * from users where name = ‘John’ or (votes > 100 and title <> ‘Admin’)
DB::table('users')
->where('name', '=', 'John')
->orWhere(function($query)
{
$query->where('votes', '>', 100)
->where('title', '<>', 'Admin');
})
->get();Laravel Aggregates
$users = DB::table('users')->count();
$price = DB::table('orders')->max('price');
$price = DB::table('orders')->min('price');
$price = DB::table('orders')->avg('price');
$total = DB::table('users')->sum('votes');
DB::table('name')->remember(5)->get();
DB::table('name')->remember(5, 'cache-key-name')->get();
DB::table('name')->cacheTags('my-key')->remember(5)->get();
DB::table('name')->cacheTags(array('my-first-key','my-second-key'))->remember(5)->get();Laravel Raw Expressions
$users = DB::table('users')
->select(DB::raw('count(*) as user_count, status'))
->where('status', '<>', 1)
->groupBy('status')
->get();return rows
DB::select('select * from users where id = ?', array('value'));return nr affected rows
DB::insert('insert into foo set bar=2');
DB::update('update foo set bar=2');
DB::delete('delete from bar');returns void
DB::statement('update foo set bar=2');raw expression inside a statement
DB::table('name')->select(DB::raw('count(*) as count, column2'))->get();Laravel Inserts / Updates / Deletes / Unions / Pessimistic Locking
Inserts
DB::table('users')->insert(
['email' => 'john@example.com', 'votes' => 0]
);
$id = DB::table('users')->insertGetId(
['email' => 'john@example.com', 'votes' => 0]
);
DB::table('users')->insert([
['email' => 'taylor@example.com', 'votes' => 0],
['email' => 'dayle@example.com', 'votes' => 0]
]);Updates
DB::table('users')
->where('id', 1)
->update(['votes' => 1]);
DB::table('users')->increment('votes');
DB::table('users')->increment('votes', 5);
DB::table('users')->decrement('votes');
DB::table('users')->decrement('votes', 5);
DB::table('users')->increment('votes', 1, ['name' => 'John']);Deletes
DB::table('users')->where('votes', '<', 100)->delete();
DB::table('users')->delete();
DB::table('users')->truncate();Unions. The unionAll() method is also available, and has the same method signature as union.
$first = DB::table('users')->whereNull('first_name');
$users = DB::table('users')->whereNull('last_name')->union($first)->get();Pessimistic Locking
DB::table('users')->where('votes', '>', 100)->sharedLock()->get();
DB::table('users')->where('votes', '>', 100)->lockForUpdate()->get();Laravel Validation
