running a script exec command from php

Question

I have an application where I need to run a PHP script by exec() function of php.

"php /var/www/server/data/scripts/ThreadHandler.php 145596 > /var/www/server/data/logs/threads/thread.145596.log 2>&1 &"

also tried

"php /var/www/server/data/scripts/ThreadHandler.php 145596 > /var/www/server/data/logs/threads/thread.145596.log 2>&1 "

I am running above command with exec() function of PHP, but it is not getting run, I can't track any error. please suggest any change.

Answer 1

try

passthru('php -f /var/www/server/data/scripts/ThreadHandler.php 145596 > 
         /var/www/server/data/logs/threads/thread.145596.log 2>&1');

Also, try to run it from linux command line

Answer 2

Try defining $output and $return_var arguments for exec and print their values :

$output = array();
$rv = null;
exec("your command", $output, $rv);
print_r($rv);
print_r($output);
