javascript - preg_match get contents of variable -

i have php preg_match , curl script gets content of specific line , displays it.

http://cdadownloader.cf link. if paste in form e.g 5640653 scrape content of http://www.cda.pl/video/5640653, preg_match

 preg_match_all("~^\s*file\s*:\s*'(.*?)',?\s*$~m", $source_code, $file); 

will inside script tags line called " file "

file: 'http://vgra012.cda.pl/13495603584734.flv?st=s5o2o-ywjbpgols3glghgg&e=1453683496', 

and contents in case

 http://vgra009.cda.pl/13495603584734.flv?st=vu78-g3noin23uy_9-mkzq&e=1453683460 

by using

substr($file[0][0], 23,-2) 

the url displayed , used.

everything works fine ( download buttons not work still have problem headers works right click save )

now have added premium player uses variable store url , have no idea how contents

$f().setclip('http://vrbx098.cda.pl/vl73f1740f66221a2168a374b86409140d.mp4?st=d-wustoxzfd4e4ugaxw4qg&e=1453679326'); 

would able point me in right direction without unnecessary comments ? :) in advance

okay, think understand wanting. here try:

preg_match("~setclip\('(.*?)'~", $page_contents, $setclip_match); $setclip_url = $setclip_match[1];
