I was wondering if there was a way to delete an item from an array in PHP? for example....


$var[1] = "stuff";
$var[2] = "http";
$var[3] = "www";
$var[4] = "etc";



and then delete one item, say, "3", and rename 4 to 3, so in the end it would be....


$var[1] = "stuff";
$var[2] = "http";
$var[3] = "etc";



Thanks in advance! :)

unset($var[3]);
$var = array_reverse(array_reverse($var));

You could also use sort to reindex.
