404 PHP how to make

Fixing 404 errors: learn how to create custom 404 pages with PHP and an example code.

Creating a PHP File

The first step to writing PHP code is creating a .php file. The .php extension tells the server that this file contains code written in the PHP language. It is common practice to name the file something that reflects the contents of the file, such as ‘register.php’ or ‘contact.php’.

To create a .php file, you can use any text editor such as Notepad, Sublime Text, or Atom. Once you have the text editor open, type any PHP code you want. As an example, type in the following code:

<?php
echo “Hello World”;
?>

Once you are finished typing, save the file with a ‘.php’ extension. For example, if you wanted to call the file ‘example.php’, you would save it as ‘example.php’.

Executing the PHP File

Now that you have created the .php file, you can execute it. To execute the file, you will need to upload it to a web server. Once the file has been uploaded, you can access it in a web browser. When you access the file, the server will read the file and execute the PHP code inside. As an example, if you uploaded the ‘example.php’ file, you would type in the URL ‘example.php’ into your web browser.

When the file is executed, the server will read the code and execute it. In this case, the server will output the text ‘Hello World’. You can also output HTML or other content, such as images and videos, using PHP.

Conclusion

Creating and executing a .php file is a relatively straightforward process. With the right tools and knowledge, you can easily create and execute your own .php files. This is a great way to create dynamic web pages that can be customized with user input, such as forms or databases.
