Delete element from array by value

[tibberous]

If I have an array, $arr = array('red', 'green', 'blue'), how can I delete green?

You can use unset() to remove array elements. For indexed arrays PHP does not reorder the index after an unset(), so you can end up with non-sequential indices.

 

unset($arr[1]);

 

Although it's possible I'm wrong, but atleast it gives you a search term for google

Right - but green is the value, not the key.

[.josh]

$arr = array('red', 'green', 'blue');

foreach ($arr as $key => $val) {
   if ($val == "green") {
      unset($arr[$key]);
   }
}

or

 

unset ($array[array_search('green', $array)]);

[tibberous]

or

 

unset ($array[array_search('green', $array)]);

 

Neat. Seems like their should be a built in function, but that's still neat.
