call_user_func_array() is nifty for calling PHP functions which use variable argument length. For
example:
<?php
$array = array(
array("foo", "bar"),
array("bat", "rat"),
);
$values = call_user_func_array("array_merge", $array);
var_dump($values);
?>
/* output:
array(4) {
[0]=>
string(3) "foo"
[1]=>
string(3) "bar"
[2]=>
string(3) "bat"
[3]=>
string(3) "rat"
}
*/
The neat feature is that $array could have any number of arrays inside it.
