array_filter() has a second parameter callback_function which is optional.
If you call array_filter() without it, it will remove all values that are
equal to the false values listed in http://de3.php.net/manual/en/language.types.boolean.php
#language.types.boolean.casting [one line link]
from the array.
Example:
$a = array(0 => 0,
1 => '',
2 => 'foo',
3 => false);
$a = array_filter($a);
