phamphong_tn's function to remove an element from an array seems a bit complicated for something that is actually quite simple.

Here's another way to remove an element from an array:

<?php
//the function
function removeArrayElement(&$arr, $index){
	if(isset($arr[$index])){
		array_splice($arr, $index, 1);
	}
}

//testing the function
$test = array("zero", "one", "two", "three");
echo "<pre>";
print_r($test);
echo "</pre>";
$this->removeArrayElement($test, 2);
echo "<pre>";
print_r($test);
echo "</pre>";

?>

output:

Array
(
    [0] => zero
    [1] => one
    [2] => two
    [3] => three
)

Array
(
    [0] => zero
    [1] => one
    [2] => three
)

To remove an element from an associative array is even simpler:

unset($arr[$index]);
