How to execute a php script from another php script?

Question

I have some PHP files called file1.php, file2.php, file3.php. Now, I want to run these PHP files one by one from other PHP file called all.php. I mean file2.php will be executed after file1.php was completed. File3.php will be executed after file2.php was completed. How to do that ?

Can I use exec function ? It is safe for my hosting ? I am using Cpanel in shared hosting. There is any way to do that but safe for my content in hosting ?

Thank you very much !

include what you need in all.php

you can use include()

include('file1.php');
include('file2.php');
include('file3.php');

or include_once()

include_once('file1.php');
include_once('file2.php');
include_once('file3.php');

or require or require_once

require 'file1.php';
require 'file2.php';
require 'file3.php';

=> require() will produce a fatal error (E_COMPILE_ERROR) and stop the script

=> include() will only produce a warning (E_WARNING) and the script will continue

when you include the file, it's as if you have the file written at the location where you have included it !!!!

Yes you can use 'exec' function or as alternate 'system', 'passthru' functions

But in that case your files i.e. 'file1.php', 'file2.php' and 'file3.php'

will execute as cli execution.
you will not get http variables like $_REQUEST, $_SESSION etc.
security is depend upon code what you written in file1.php.
you code will execute as a permission of apache user if you are calling all.php from web url (so probably it will be safe).
