[SOLVED] delete variable from array not by key

[blurrydude]

I tried several variations of unset and some different array_diff combinations, but i cant seem to do this:

 

the script needs to take an array, examine it to find a specific value that the user will input and then remove it from the array.

 

i.e.:

 

array - red yellow orange

 

user inputs yellow

 

array - red orange

 

seems simple, but I can't seem to figure out how without first knowing the key.

//$_POST['colour'] = "yellow";

$array = array(0 => 'yellow', 1 => 'red', 2 => 'orange');

$key = array_search($_POST['colour'], $array); // $key = 1;
unset($array[$key]);
?>

Should work, untested though. It assumes $_POST['colour'] contains the name of the element to be removed.

You could simplify it by doing:

<?php
//$_POST['colour'] = "yellow";
$array = array(0 => 'yellow', 1 => 'red', 2 => 'orange');
unset($array[array_search($_POST['colour'], $array)]); // $key = 1;
?>

Thanks, works fine. I knew I was missing something simple.
