<?
Multidimensional array searching to return key if value found
I need to pass in a name to a search function on an array.
If then name is found I need to return the key associated with the value.
this was my first pass, with an array and it works
$radioreps = [
'7' => 'Larry',
'8' => 'Kelly',
'9' => 'Dave',
'10' => 'Dana',
'11' => 'Silver',
'12' => 'Lueth',
'17' => 'Mike',
'34' => 'Ennen',
];
if(in_array($username, $radioreps)) {
$key = array_search($username, $radioreps);
return $key;
}
return false;
although the value being passed in might be a first or last name, so i needed to associate multiple names to one key.
like so:
$radioreps = array(
'7' => array('Larry', 'Fredrickson'),
'8' => array('Kelly', 'Steve'),
'9' => array('Dave', 'David', 'Burns'),
'10' => array('Dana', 'Burress'),
'11' => array('Silver', 'Marsha'),
'12' => array('Elaine', 'Lueth'),
'17' => array('Mike', 'Haile'),
'34' => 'Ennen',
);
foreach($radioreps as $rep){
if(($strict ? $rep === $username : $rep == $username) || (is_array($rep) && in_array($username, $rep, $strict))) {
$key = array_keys($rep);
dd($key);
return $key;
}
}
return false;
not sure i'm doing this right though. but i want my end results to be if Fredrickson is passed in, then the key 7 should be returned, and so on.
............You Can Try This Trick----------
this did the trick
$radioreps = [
['id' => 7, 'name' => 'Larry'],
['id' => 7, 'name' => 'Fredrickson'],
['id' => 8, 'name' => 'Steve'],
['id' => 8, 'name' => 'Kelly'],
['id' => 9, 'name' => 'Dave'],
['id' => 9, 'name' => 'David'],
['id' => 9, 'name' => 'Burns'],
['id' => 10, 'name' => 'Burress'],
['id' => 10, 'name' => 'Dana'],
['id' => 11, 'name' => 'Marsha'],
['id' => 11, 'name' => 'Silver'],
['id' => 12, 'name' => 'Elaine'],
['id' => 12, 'name' => 'Lueth'],
['id' => 17, 'name' => 'Mike'],
['id' => 17, 'name' => 'Haile'],
['id' => 34, 'name' => 'Ennen'],
];
foreach($radioreps as $key => $rep)
{
if (in_array($username, $rep)) {
echo "Found {$rep['id']} for {$username}" . PHP_EOL;
return $rep['id'];
}
}
return false;
