PHPMyAdmin is an open source tool for managing MySQL databases. It is usually used for database management and query operations. However, when using PHPMyAdmin, you may encounter the problem of file not being found, which is a very troublesome problem for developers who need to perform database management in PHPMyAdmin. So in this article, we will explore the various reasons that may cause the file not found problem and provide corresponding solutions.

First of all, we need to understand some common error messages that PHPMyAdmin cannot find the file:

  1. Cannot find phpmyadmin.css, such as the example error message: "The requested URL /phpmyadmin /phpmyadmin.css was not found on this server."
  2. The JavaScript file could not be found, such as the sample error message: "Uncaught ReferenceError: $ is not defined".

If you encounter the above error message when using PHPMyAdmin, it means that you also encountered the problem of not being able to find the file. Next let us take a look at what causes these problems.

  1. Configuration Error

PHPMyAdmin’s configuration file usually exists on the web server where the MySQL server is located, such as Apache or IIS. This configuration file is usually set to config.inc.php and needs to contain some parameters related to the MySQL server, such as the IP address, port number, user name and password of the MySQL server. Therefore, if these parameters are set incorrectly, PHPMyAdmin will not be able to find the config.inc.php file, causing file not found problems.

To solve this problem, you need to open the config.inc.php file and check whether the parameter settings are correct. Among them, the most common mistake is to add a semicolon or lack a semicolon when assigning values ​​to parameters. Therefore, when checking, it is best to carefully look at the assignment statement of each parameter to ensure that there is no problem with the syntax.

  1. File damage

The function of PHPMyAdmin is implemented through PHP code, so it needs to rely on some PHP extension modules, such as mysqli and mbstring. If these extension modules are not installed or installed incorrectly, PHPMyAdmin will not be able to run normally, resulting in the problem of file not being found.

To solve this problem, you need to log in to the server and check the PHP configuration file php.ini. In this file, you need to ensure that the mysqli and mbstring extension modules are correctly enabled. If these extensions are not installed, you can resolve this issue by downloading and installing the appropriate PHP extensions.

  1. File permissions

PHPMyAdmin usually stores some temporary files in the server's temporary directory. If PHPMyAdmin does not have the appropriate permissions to access these directories, it will cause file not found problems.

To solve this problem, you need to log in to the server and check the permissions of the server's temporary directory. You need to make sure that PHPMyAdmin has sufficient permissions to access this directory and can create temporary files in it. In Linux systems, you can use the chmod command to change the permissions of a file or directory. On Windows systems, you can use the Properties window to change permissions on a file or directory.

To sum up, the problem that PHPMyAdmin cannot find files can be solved by checking the server configuration, file integrity and file permissions. With a deeper understanding of the above three inspections, you will be better able to diagnose and resolve such problems.
