What is the relationship between the php.ini file and displaying MySQL errors using mysql_error()?

The php.ini file contains configuration settings for PHP, including error reporting levels. To display MySQL errors using mysql_error(), you need to ensure that error reporting for MySQL is enabled in the php.ini file. You can do this by setting the error_reporting directive to include E_ALL or E_WARNING. Once this is done, you can use mysql_error() to display MySQL errors in your PHP code. 

// Enable error reporting for MySQL in php.ini
// Set error_reporting directive to include E_ALL or E_WARNING

// Example PHP code to display MySQL errors using mysql_error()
$conn = mysqli_connect("localhost", "username", "password", "database");

if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

$query = "SELECT * FROM non_existent_table";
$result = mysqli_query($conn, $query);

if (!$result) {
    echo "Error: " . mysqli_error($conn);
}

mysqli_close($conn);
