 New Comment:

now I have to write..

if ($lim === null) {
    $parts = explode(',', $str);
} else {
    $parts = explode(',', $str, $lim);
}

..instead of..

$parts = explode(',', $str, $lim);

Isn't it some sort of crap ?..

So what should I give to $limit to explode unlimited ???... As I know -
in PHP no parameter means some default value - what default value is
defined to default $limit ?..

Yes, null == 0. (PHP is still loose typed language..)

Description:
------------
explode() do not explodes string if $limit argument is null, but
explodes if no $limit argument given.

Reproduce code:
---------------
print_r(explode(',', 'a,b,c'));
print_r(explode(',', 'a,b,c', null));

Expected result:
----------------
Array
(
   [0] => a
   [1] => b
   [2] => c
)
Array
(
   [0] => a
   [1] => b
   [2] => c
)


Actual result:
--------------
Array
(
   [0] => a
   [1] => b
   [2] => c
)
Array
(
   [0] => a,b,c
)
