Check preg_last_error().

I read somewhere (right now I don't remember where) there is problem
with long regular expressions in php5. Is that true? I made the regular
expression shorter, now the script works (with some limitations due to
the short regex).

Description:
------------
I have a code for url rewrite, I use the preg_match function to
separate the GET parameters.
The code works fine in PHP 4.4.4, I get a matches array with the GET
parameters. But it doesn't work on PHP 5.28, the matches array is
empty.
I was checking the documentation and It seems there are not changes on
this function.
Reproduce code:
---------------
$url="http://localhost/test+param-2009.html";
preg_match("/\/[^+]*\+?[^+]+\++([^-]*)-?([^-]*)-?([^-]*)-?([^-]*)-?([^-]*)-?".
"([^-]*)-?([^-]*)-?([^-]*)-?([^-]*)-?([^-]*)-?([^-]*)-?([^-]*)-?([^-]*)-?([^-]*)-?".
"([^-]*)-?([^-]*)-?([^-]*)-?([^-]*)-?([^-]*)-?([^-]*)\.html/i", $url,
$parameters);
print_r($parameters)
Expected result:
----------------
/*tested on PHP 4.4.4
Array ( [0] => //localhost/test+param-2009.html [1] => param [2] =>
2009 [3] => [4] => [5] => [6] => [7] => [8] => [9] => [10] => [11] =>
[12] => [13] => [14] => [15] => [16] => [17] => [18] => [19] => [20] =>
)
Actual result:
--------------
Array ( )
