I have a simple preg_match statement... When I test this on eg. regex101.com, everything that I want gets selected. But when I set this to my script it brings nothing!
$params['filename'] = "2013-00049_20130830.pdf";
$pattern = '/([0-9]{4,8})/gm';
preg_match( $pattern, $params['filename'], $tmp);
print_r($tmp);
What I expact is an array like
Array
(
[0] => 2013
[1] => 00049
[2] => 20130830
)
but there is not such thing... what am I doing wrong ???
