I want to process my access log in php - checking some IPs, which are leeching content and so on, everything in PHP, running as CLI. I tried to make following, but it never pass exec tail -f, so, actually I can not process the data. Any help appreciated.
$log = '/var/log/lighttpd/web.org-access.log';
$pipefile = '/www/web.org/tmp/fifo.tmp';
if(file_exists($pipefile))
if(!unlink($pipefile))
die('unable to remove stale file');
umask(0);
if(!posix_mkfifo($pipefile,0777))
die('unable to create named pipe');
exec("tail -f $log > $pipefile 2>&1 &"); //I tried nohup and so on...
//exec("varnishncsa $log > $pipefile 2>&1 &"); //will be here instead tail -f
echo "never comes here"; //never shows up
If possible, I want to do it just in PHP, no bash/tcsh scripting (I know how to do it using those).
Thanks.
If you want exec to start a background process, you will have to redirect its output.
Quote from the manual:
If a program is started with this function, in order for it to continue running in the background, the output of the program must be redirected to a file or another output stream. Failing to do so will cause PHP to hang until the execution of the program ends.
Notice the full syntax description:
string exec ( string $command [, array &$output [, int &$return_var ]] )
