Description:
------------
Error in Documentation

http://uk.php.net/explode
array explode(string $delimiter, string $string [, int $limit = -1])

The default value for $limit is not -1. I assumed it would be 0, but that does not output what I expected either. The default appears to be a value that cannot be set, ideally this should be made clear in the documentation.

Another bug is listed saying the default value for $limit is 0, if the documentation has been updated to show this, the documentation will still be wrong.




Reproduce code:
---------------
$string = 'path/to/folder/';
$array = explode('/', $string);
print_r($array)
Output: Array ( [0] => path [1] => to [2] => folder [3] => )

$string = 'path/to/folder/';
$array = explode('/', $string, -1);
print_r($array)
Output: Array ( [0] => path [1] => to [2] => folder )


$string = 'path/to/folder/';
$array = explode('/', $string, 0);
print_r($array)
Output: Array ( [0] => path/to/folder/ )


Expected result:
----------------
http://uk.php.net/explode
array explode(string $delimiter, string $string [, int $limit])

Actual result:
--------------
http://uk.php.net/explode
array explode(string $delimiter, string $string [, int $limit = -1])
