MySQL Connection Not Working: Addressing Hostname

When attempting to establish a MySQL connection via PHP, you may encounter the error "No such file or directory" (error code 2002). This error often indicates that MySQL is unable to locate a specified file or path.

One potential cause of this error is an incorrect hostname specified when connecting to MySQL. Instead of using "localhost," which usually refers to the local machine, the issue can be resolved by using the IP address of the host machine (e.g., 127.0.0.1).

To address this issue, modify your MySQL connection code as follows:

$conn = mysql_connect('127.0.0.1', 'USER', 'PASSWORD');

By specifying the IP address directly, you ensure that MySQL is connecting to the correct host, resolving the "file or directory" error. Note that this is a temporary solution and may indicate an underlying issue with your host configuration.
