How does the use of mysql_pconnect() impact performance in PHP?

Using mysql_pconnect() in PHP can impact performance by creating persistent connections to the MySQL database server, which can lead to resource exhaustion and slow down the server. It is recommended to use mysql_connect() instead for non-persistent connections to avoid these performance issues. 

// Connect to MySQL database using mysql_connect() instead of mysql_pconnect()
$servername = "localhost";
$username = "username";
$password = "password";

$conn = mysql_connect($servername, $username, $password);

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

echo "Connected successfully";
