How can one test the server load impact of using set interval for chats in PHP?

Using set interval for chats in PHP can potentially lead to high server load due to the continuous polling of the server. To test the server load impact, you can simulate multiple users making requests to the server at the same time and monitor the server's resource usage. One way to mitigate this issue is to implement a more efficient method such as WebSockets for real-time chat functionality. 

// Simulate multiple users making requests to the server
for ($i = 0; $i < 1000; $i++) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'http://yourserver.com/chat.php');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_exec($ch);
    curl_close($ch);
}
