What are common issues with using MySQL functions in PHP code?

One common issue with using MySQL functions in PHP code is the deprecation of the mysql extension in favor of mysqli or PDO. To solve this issue, you should update your code to use mysqli or PDO functions instead of mysql functions. 

// Connect to MySQL using mysqli
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
