preg match - return shell_exec then preg_match -

here's pretty weird:

$txt = '/some/dir/some/file.txt'; $content = shell_exec('cat "'.$txt.'"'); 

then:

preg_match_all("![some regex]!", $content, $matches); 

but preg_match returns nothing/false since $content "seems" empty (while it's txt file being filled infos: wget output of download in progress).

weird thing is, if do:

echo $content; exit; 

it shows current content of txt file. when f5/refresh, content accurately updated , print again. preg_match still can't parse it...

$content = shell_exec('cat "'.$txt.'"' 2>&1); 

isn't doing better.

nb: path file correct, chmod correct, etc...

i tried following:

$content = file_get_contents(dirname(__file__).'/'.$txt, true); 

or

$ch_txt = curl_init(); curl_setopt($ch_txt, curlopt_url, dirname(__file__).'/'.$txt); curl_setopt($ch_txt, curlopt_returntransfer, 1); curl_setopt($ch_txt, curlopt_followlocation, 1); $content = curl_exec($ch_txt); curl_close($ch_txt); 

and same behaviour goes on!

i've never seen funny.

additionnal info:

the regex is:

preg_match_all("!([0-9a-za-z]+)([ \.]+)([0-9]+)% ([0-9\.a-za-z]+) ([0-9a-za-z]+)!", $content, $matches); 

the file content like:

323600k .......... .......... .......... .......... .......... 49%  114k 36m48s 323650k .......... .......... .......... .......... .......... 49%  249k 36m47s 323700k .......... .......... .......... .......... .......... 49%  116k 36m47s 323750k .......... .......... .......... .......... .......... 49%  242k 36m47s 323800k .......... .......... .......... .......... .......... 49%  114k 36m46s 323850k .......... .......... .......... .......... .......... 49%  237k 36m46s 

output of this:

system("wget '".$file_to_download."' --load-cookies=".$directory."cookie.txt --output-document='".$directory.$new_directory."/".$output."' -p ".$directory." --output-file='".$directory.$output.".txt' -b >/dev/null 2>&1"); 

preg_match_all("!([0-9a-za-z]+)([ \.]+)([0-9]+)%([ ]+)([0-9\.a-za-z]+) ([0-9a-za-z]+)!", $content, $matches);
