Question

In the below code, how do I check if $variable equals “$one”.

<?php  
    $one = array (1,2,3);
    $two = array (4,5,6);

    $variables = array ($one, $two);

    foreach ($variables as $variable){
        //check if the $variable is equal to "$one"
            //do stuff that is specific for array $one
    }   
?>

Simply put, you can’t. You can add a key to the values though:

<?php  
$one = array (1,2,3);
$two = array (4,5,6);

$variables = array ( 'one' => $one, 'two' => $two);

foreach ($variables as $key => $variable){
    //check if the $variable is equal to "$one"
    if( $key === 'one' ) {
        //do stuff that is specific for array $one
    }
}
