execute linux command background in php

Question

I need to execute a command in linux by using php and it should meet following requirement.

I know how to do it separately,

with log file :

shell_exec("command 1>log 2>&1");

as background:

shell_exec("command /dev/null 2>&1 &");

My question is how to do it together ?

Actually your second example does not run the command "in background" by which people typically mean "without the calling process to wait for it to finish". You need to detach the controlling console for that: shell_exec("nohup command /dev/null 2>&1 &"); — arkascha
