Get index of element in an array by the value

Question

I have this array in PHP:

array(
    [0] => array( \'username\' => \'user1\' )
    [1] => array( \'username\' => \'user2\' )
)

Answer 1

Take a look at array_search.

From the PHP help file:

 'blue', 1 => 'red', 2 => 'green', 3 => 'red');

$key = array_search('green', $array); // $key = 2;
$key = array_search('red', $array);   // $key = 1;
?>
