Why Am I Getting a 'No Such File or Directory' Error When Connecting to MySQL from PHP?

Troubleshooting MySQL Connection Error: "No Such File or Directory"

When establishing a connection to a MySQL database from PHP, you may encounter the error "2002 - No such file or directory." This error typically indicates that the specified file or directory could not be found by PHP.

Specifically, in the provided PHP code, the connection is attempted using 'localhost' as the hostname. However, in the updated information, you mentioned that the socket is located at /tmp/mysql.sock. This suggests that the hostname should be updated to:

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

Additionally, ensure that the PHP code is using the correct path for the mysql.sock file. In your case, this would be:

mysql.default_socket = /tmp/mysql.sock

By updating the hostname and ensuring the mysql.sock path is correct, you should be able to establish a successful connection to your MySQL database.
