Get variable name in PHP

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
    }   
?>

Please clarify your question. Do you want to just check if $variable is equal to $one or no? if($variable == $one) { //Do things } — Miro Markaravanes

$variable == $one does this not work for you. Array can be compared as variables — Shakti Singh

Do you have the ability to place indexes of the array values: 'one' => $one, 'two' => $two... — Rolice

This question doesn't make a whole lot of sense. Please clarify what you are trying to do exactly and why. — deceze

$three = array (1,2,3); $variables[] = $three;. That will execute the // do stuff twice.

if this is really what the OP wants, the question should be closed because it's not a real question asking how to do an IF block.

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
    }
}

Why the downvote? Is this not a viable alternative to getting the name of a variable?

Thank you, this was the solution I was looking for.

  foreach ($variables as $variable){
        if($variable == $one)//TRUE if $a and $b have the same key/value pairs.
        {

        }
    }

And if you want to check for order and types as well you can do as follow:

  foreach ($variables as $variable){
        if($variable === $one)
        {

        }
    }

You can check with

if($variable===$one)

You are taking multi dimensional array. Keep in mind and you need to check with "===", not with "==" because its not an variable or even a string.
