As you already know, with javascript and other lenguages in the web we need to create a special tag to link several files.js into html files. An example of this is as follows:
<script src="js/myscript.js"></script> // This is in a html file
In php we can do something like this with the reserved word include. We can use it as follow:
<html>
<head>
<title>This is a sample</title>
</head>
<body>
<?php
include "index.php";
?>
</body>
</html>
First, I am using a html file and embedded in it there is a php script. In this little code we have only one line of code where we are invoking a php file which content is the following:
<?php
for($x = 0; $x <= 100; $x++){
if($x%2 == 0){
echo "$x\n\t\t";
$x++;
}else{
$x++;
}
}
?>
So, this is a way how we can include php files from others file either in the same carpet or in other.
The advantages of doing this are the following:
- Our html file is cleaner
- We can reuse code
- Is easier and better than copying and pasting code
