In PHP, the include and require keywords copies the contents of one file into other file.
This is useful for making a file (such as the header section of a web page) which is included into many web pages.
include is optional: if the specified file does not exist, PHP ignores the include.
require is not optional: if the specified file does not exist, PHP generates an error.
Contents
Example
Here is a PHP page named message.php, which contains some text.
Hello World!
Here is a PHP page named some-page.php:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>HTML 5 example: minimum required elements</title> </head> <body> <?php include 'message.php'; ?> </body> </html>
In the above example, some-page.php includes the Hello World! text.
Syntax
The word include (or require) followed by the filename (in quotation marks, either single or double).
If the included file is in a different folder from the file containing the include statement, then the path to the file must be included:
<?php include '../message.php'; ?>
