Array element

[Cogen]

Does anyone know if there is a function to delete an element of an array? For instance ...

$test = array("1","2","3","4","5");
count($test) // this is 5

//Delete $test[2] here

now the array is ("1","2","4","5");
count($test) // this is 4

have a look at array_slice() that should give you some direction

[Roman_Totale]

unset($test[2] );

Thanks for the reply's guys ..

Roman Totale .. It didn't work for me. There were unexpected results.

stolzyboy .. That's the direction I needed, thank you. Here is what I'm using (I found it on the page that you linked to above).

function remove_one_element($array,$index_to_remove){
	//$index_to_remove : type integer
	$index_nb_elements=count($array)-1;
	switch($index_to_remove){
	case 0:
		$array = array_slice($array, 1);
	break;
	case $index_nb_elements :
		$array = array_slice($array, -1);
	break;
	default:
		$array_start = array_slice($array,0, $index_to_remove);
		$array_end = array_slice($array, $index_to_remove+1);
		$array = array_merge ($array_start, $array_end);
	break;
	}
	return $array;
}

oops, the case...

case $index_nb_elements :
$array = array_slice($array, -1);
break;

... should be ...

case $index_nb_elements :
$array = array_slice($array, 0, -1);
break;
