Well, the code below posted by anonymous does work but sometimes you also want to filter all white
spaces. Here's another trick.
<?php
$array = array(5, " ", 2, NULL, 13, "", 7);
print_r($array);
$result = array_filter($array, create_function('$a','return
trim($a)!="";'));
print_r($result);
?>
Array
(
[0] => 5
[1] =>
[2] => 2
[3] =>
[4] => 13
[5] =>
[6] => 7
[7] =>
[8] => 4
[9] =>
)
Array
(
[0] => 5
[2] => 2
[4] => 13
[6] => 7
[8] => 4
)
