Why does i get this error?

[judgemen]

#1064 - You have an error in your SQL syntax; check the manual  that corresponds to your MySQL server version for the right syntax to  use near '<?php
// MYSQL
$conn = mysql_connect("localhost", "judgemen", "MYPASS")' at line 1

This is what im trying to add.

<?php
// MYSQL
$conn = mysql_connect("localhost", "judgemen", "MYPASS");
mysql_select_db('judgemen_donate', $conn);
?>

The error tells you exactly what's wrong. It indicates you're trying to execute PHP as an SQL query.

The mysql extension is outdated and on its way to deprecation. Instead, use PDO, which has many useful improvements, such as prepared statements and support for the Traversable interface, so you can loop over results with foreach. If you need a PDO tutorial, try "Writing MySQL Scripts with PHP and PDO".
