PHP include external file!!

[gaptrast]

Hello I am using php include on my site to save both time and work.

My website:

file1.php
index.php
file2.php
/exempl/index.php
/exempl/super.php
/exempl/super2.php

How can I use the php include to include file1.php and file2.php in /exempl/index.php???

I have tried this:

<?php

include 'http://www.example.com/file1.php';

?>

BUT IT DO NOT WORK

I DESPERATELY NEED HELP QUICK!!!

Including from a remote URL is not allowed, even if that URL is actually local. The simplest way is to use either relative or absolute paths to the files:

//This is relative, '../' means the parent directory
include('../file1.php');

//This is absolute, '/' means the base directory
include('/file1.php');
//If the base is not setup to the document root, it may actually be:
include('/home/YOURCPANELUSERNAME/public_html/file1.php');

Both of these will work in the '/exempl/index.php' file.

The only difference between require() and include() is that if an include fails, it errors. If a require fails, it freaks out and stops the page loading (in a good way). Therefore, you should use require() for includes files.

You can also use require_once() and include_once(). These are pretty much the same, but it will only include or require the file once, even if you tell it to require it twice. I can't actually see the point in _once, but it's good to know about.

This can be useful when you have a complex system that is set to include or require a class's file each time it must be used. If you used the same class over and over, and it's a quite big file, it can slow down the script processing. However, if you called a _once method, the class will be loaded in the main script only once, saving some considerable overhead.

I can't actually see the point in _once, but it's good to know about.

If you require or include a file, that file actually runs. ie, if you include foo.php and foo.php opens a log file, database connection, etc, then include-ing it twice will repeat the action, often not what you want.

Also, if foo.php defines a function, you will get a nasty little warning message like:

Fatal error: Cannot redeclare foobar() (previously declared in /home/zeke/public_html/foo.php:6) in /home/zeke/public_html/foo.php on line 7

It's better to not rely on _once - the code should be fixed so that it doesn't include the file more than once.

In some cases it is just not feasible. You include B.php and C.php which both include A.php.
And if you have several conditional requires, using require_once is simpler and less error prone than manually keeping track of which files have already been called.

[callumacrae]

Fair enough, I guess.

<?php
include('exempl/index.php');
include('exempl/super.php');
?>

I think you should code like that.Because some servers were configured to process your code like "../somefile.php" or "/somefile.php" to "root/somefile.php" but another think "/somefile.php" is the peering file
