Delete Item from Array

[Dysan]

How do I search for an item within an array, then delete it?

Well... you could pass something in the url such as example.php?action=add&id=1 or example.php?action=del&id=1... or you could just pass an id and if it exists delete it and if it doesn't add it.  Depends on what its for and what you want it to do... but the code would look something like this...

<?php
  $id = $_GET['id'];
  $action = $_GET['action'];
  switch($action){
  case 'add':
    $myArray[$id] = something;
    break;
  case 'del':
    unset($myArray[$id]);
    break;
  }
?>

LOL... you should have just reposted... you completley changed your question...

Do you want to search for a value... or an id?

 

I'll assume you are wanting to pass an id and if it is there then delete it, if not create it.

 

<?php
$id = $_GET['id'];
if(isset($myArray[$id])){
  unset($myArray[$id]);
} else {
  $myArray[$id] = something;
}
?>

<?php


//delete all the array values that match $search
function filter_array ($array, $search)
{
foreach(array_keys($array, $search) as $k)
	unset ($array[$k]);
return $array;
}

?>

 

 

Orio.
