An image can be run as a php script? The answer is yes. In this tutorial, we will use an example to illustrate you how to do.
You can open your .htaccess and add content below.
RewriteEngine on RewriteRule ^(.*?).png$ test.php?q=$1
Create a php file
This file is called to test.php, you can add content below.
<?php echo $_GET["q"]; ?>
Open a url that ends with .png
For example, you open url: http://127.0.0.1/test/123.png
You will get the result:123
The file type of 123.png is an image, however, it runs a php code.
