I've spent a while on this but can't get this to work, I apologize as I asked a somewhat related question about this earlier but deleted it so I could do more research to narrow down the question, at this point I am stuck as I thought I had the solution with this but its not working as I expect.. I found a forum where someone asked a similar question and they gave code like below, which I am trying.. it does run the script, but it still waits for it to finish before going to the next line in the PHP code
proc_close(proc_open ("/var/www/other_scripts/perl/apps/emails_extract_from_url.pl \"$stoopid\"", array(), $foo));
Some of my code when i played around with proc_open
I had issues with proc_close (10 to 30 seconds) so i just killed the process using linux command kill
