Question

How to execute a php script from another ?

I want to execute 3 php scripts from my php file without waiting for the 3 scripts to finish. In other words, the 3 php files need to be executed all at once (parallel) instead of one-by-one (sequentiell).

The 3 scripts are in the same folder of my main php file (script).

Answer 1

If you do not want to wait for them to finish, run them with either

exec('php script.php &> /dev/null &');
shell_exec('php script.php &> /dev/null &');
system('php script.php &> /dev/null &');
`php script.php &> /dev/null &`

Any of those should accomplish the job, depending on your PHPs configuration. Although they are different functions, their behaviour should be similar since all output is being redirected to /dev/null and the proccess is immediately detached.

I use the first solution in a production environment where a client launches a bash SMSs sending script which can take up to 10 minutes to finish, it has never failed.
