Description:
------------
Greedy match doesn't match more than 99997 characters. If you try to
greedy match
more than 99997 characters it matches nothing.
Test script:
---------------
// 99997 string length
$contents = '';
for ($i = 0; $i < 99997; ++$i) {
$contents .= "a";
}
preg_match('/^a*?$/', $contents, $match);
var_dump($match);
// 99998 string length
$contents = '';
for ($i = 0; $i < 99998; ++$i) {
$contents .= "a";
}
preg_match('/^a*?$/', $contents, $match);
var_dump($match);
Expected result:
----------------
To match the whole $contents content in both cases.
Actual result:
--------------
The first case match the whole $contents content, but in the second one
it match
nothing.
