How can I run a program in the background (non blocking) with php?

Question

I want to run a shell script in php, but this shell script takes a long time to execute (it has sleep in it), I don\'t want the web server to block when executing this scrip

Answer 1

I solved the problem by adding

"> /dev/null 2>/dev/null &"

after the script name to the shell_exec() php function

Thanks
