What are common pitfalls or errors to look out for when using mysql_connect in PHP scripts?

Common pitfalls when using mysql_connect in PHP scripts include not properly handling connection errors, not securely storing database credentials, and not closing the database connection after use. To solve these issues, always check for connection errors, store credentials securely in a separate configuration file, and close the connection when done. 

// Connect to MySQL database
$host = 'localhost';
$username = 'root';
$password = 'password';
$database = 'my_database';

$connection = mysql_connect($host, $username, $password);

if (!$connection) {
    die('Could not connect: ' . mysql_error());
}

// Use the database connection

// Close the connection
mysql_close($connection);
