#47727 [Bgs->Opn]: Error in Documentation: explode()
ID: 47727
Updated by: mattwil@php.net
Reported By: me at lukearmstrong dot co dot uk
-Status: Bogus
+Status: Open
Bug Type: Documentation problem
Operating System: n/a
PHP Version: Irrelevant
New Comment:
Reopening this one since it's actually about the documentation problem.
(See the other bugs referenced above.)
That -1 shouldn't be there since it's misleading. The default is just
"unlimited," or the length of the input string, or PHP_INT_MAX, etc.

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])
