Hi guys, in this article we are going to understand how to include another file in PHP. First of all, we need to understand the concept of Including a file; you can insert the content of one PHP file into another PHP file before
the server executes it, with the include() or require() function. The whole process is done under XAMPP server.
The Two functions are identical
- include() generates a warning, but the
script will continue execution.
- require() generates a fatal error, and the
script will stop.
include() function in PHP
The functionality of the include function is like it involves to take all the
content in a specified file and includes it in the current file. This function
is used to generates a warning, but the script will continue execution.
Let us understand the concept with the some example to clarify the function,
consider that you have a standard header file, called "function.php". To
include the header file in a page, use the include() function.
<html>
<body
bgcolor="pink">
<h3>WORLD
CRICKET BIGGEST EXCITEMENT<h3><hr
/>
<?php
function
writeName()
{
echo
"India vs
Australia";
}
echo
"Upcoming
Tour : ";
writeName();
?>
</body>
</html>
Saved it as function.php
Now the script given
below is the implementation part of the include() function
<html>
<body>
<?php
include("function.php");
?>
// This is include function that is using the function.php

require() function in PHP
The functionality of require
function is identical to include(), except that it handles errors
differently. This function is used to generates a fatal error, and the script
will stop.
Error handing by require() & include()
Firstly, we will understand that how will the include() tackle with errors,
if we run the php script on the browser it will display output with warnings. Let us see that whole concept with example.
<html>
<body>
<?php
include("wrongfile.php");
?>
// This is include
function that show output with warnings.

Secondly, same concept with require(), if we run the above script with require()
we will find some difference from above output, difference is that
if we run the include.php script on the browser it
will only display warning & fatal errors, not the output.
<html>
<body>
<?php
require("wrongfile.php");
?>
// This is require
function that show warning & fatal error only not output.
