如何将一个PHP文件的内容包含在另一个主文件中？

Question

//Grab and assign List ID from confirmation URL 
$L = $_GET["L"]; 

//Set Redirects based on List ID  
if($L == "1") { 
header("Location: http://stat.domain.com/");
exit();
}  

This is the content of a redirection rule that I have created, but I am thinking of putting these in a separate file instead of the master file MASTER.php. I was reading online and there are different ways of reading the content off a separate file, of which are functions like include() include_once(). However, after reading through some information online, i am still not very sure what i should do to include the above content in the master file.

Any efficient way of doing this?

Answer 1

You only want to include that file once in a certain place. Perhaps add an include to redirects.php from master.php :

require_once 'redirects.php';

You could also use include_once , but that will not halt the script if the file cannot be found and will fail silently - which is usually much worse than explicitly.
