In this tutorial, we are going to learn about
PHP Include Files. This is a useful idea, you can able to include a PHP file to another PHP script or into your HTML source code on multiple pages of your system or website. For short, this function analyze and work in a specific file. The
include() functions grant you to do this.
PHP Include Files can be used multiple times and single time.
Example
Multiple Times
<?php include("footer.php"); ?>
Single Time
<?php include_once("footer.php"); ?>
We have two PHP functions that we can use to include one PHP file to another PHP file.
- The include() Function
- The require() Function
Syntax
<?php include("filename"); ?>
or
<?php require("filename"); ?>
PHP Include Example
We create a simple footer. Save as
"footer.php".
<?php
echo "<p style='font-size:18px; text-align:center;'>Copyright © ". date('Y') .", Free source code, tutorials and articles</p>"; ?>
To include this in the footer section in our page, use the
include function.
Then, create simple page. Save as
"index.php".
<!DOCTYPE html>
PHP Include File
.blink_text {
-webkit-animation-name: blinker;
-webkit-animation-duration: 1s;
-webkit-animation-timing-function: linear;
-webkit-animation-iteration-count: infinite;
-moz-animation-name: blinker;
-moz-animation-duration: 1s;
-moz-animation-timing-function: linear;
-moz-animation-iteration-count: infinite;
animation-name: blinker;
animation-duration: 1s;
animation-timing-function: linear;
animation-iteration-count: infinite;
color:black;
}
@-moz-keyframes blinker {
0% { opacity: 1.0; }
50% { opacity: 0.0; }
100% { opacity: 1.0; }
}
@-webkit-keyframes blinker {
0% { opacity: 1.0; }
50% { opacity: 0.0; }
100% { opacity: 1.0; }
}
@keyframes blinker {
0% { opacity: 1.0; }
50% { opacity: 0.0; }
100% { opacity: 1.0; }
}
