This stumped me badly in my present  project. Is this a bug or a feature in
PHP? I am trying to split a string into two, where only one half (and the

=======================
[EMAIL PROTECTED] ~]$ cat s1.php
<?php
 print count(split(',', 'a,b'))."\n";
 print count(split(',', 'a,'))."\n";

[EMAIL PROTECTED] sql]$ php -q s1.php

If your expand your example slightly, as I did, you will see why you are 
 getting the expected results:

[EMAIL PROTECTED] burhan $ cat s1.php
<?php
 $results = split(',', 'a,b');
 print_r($results);
 print count($results)."\n";
 $results = split(',','a,');
 print_r($results);
 print count($results)."\n";
?>
[EMAIL PROTECTED] burhan $ php -q s1.php
Array
(
    [0] => a
    [1] => b
)
2
Array
(
    [0] => a
    [1] =>
)
2
As you can see, the array contains an empty second element because 
(correctly) there isn't a second element after the last ,.

So, is this a bug? Not from my point of view. Its more bad input, 
expected result :)
