Delete the index array from foreach?

Question

Simple question; How can i delete the right Array from my foreach() ?

foreach ( $items as $e):
    if ( $e['seat'] == $users[$clientID]['seat']):
        //It's done, delete it.
        unset ( $e );
    endif;
endforeach;

unset($e) doesn't seem to work properly. What is the right solution to delete the right array from the right index?

This is an alternative to the for-loop given by xbonez, by passing the key value as well:

foreach ( $items as $key => $e):
    if ( $e['seat'] == $users[$clientID]['seat']):
        //It's done, delete it.
        unset ( $items[$key] );
    endif;
endforeach;

I prefer this version, but it doesn't really matter!

Doing unset($e) in a foreach unsets the variable $e, not the item in the array that it represents. You would need to use a a regular for-loop for this

for($i = 0; $i < count($items); $i++) {
   if ($items[$i]['seat'] == $users[$clientID]['seat']) {
      unset($items[$i])
   }
}

`for ($arr as $key => $val)` would be better since your answer is limited to non-associative arrays. – Corbin Jan 13 '13 at 21:53

try something like:

foreach ($items as &$e):
    if ($e['seat'] == $users[$clientID]['seat']):
        //It's done, delete it.
        unset ($e);
    endif;
endforeach;
