1. What is PHP file 404 error?
PHP file 404 error means that when accessing the website page, the browser cannot find the requested PHP file and returns a 404 error page. This error is usually caused by the PHP file being in the wrong location or file name, the file being deleted or moved, or the server being set up improperly.

When a 404 error occurs, first check whether the path and file name of the PHP file are correct. If the path or file name is wrong, you can fix the problem by modifying the path or file name, or by moving the file to the correct location.
If the file path and file name are correct, but a 404 error still occurs, you need to confirm whether the file exists. You can view the website file directory through tools such as FTP or control panel. If the file does not exist, you need to re-upload or create the file.
If the file exists and the path and file name are correct, but you still get a 404 error, it may be caused by improper server settings. You can check whether the .htaccess file exists in the root directory of the website. If it exists, you may need to check whether the code in it is correct. At the same time, you can also try to clear the browser cache and cookies, or contact the server administrator for assistance.
