What methods can be used to limit CURL traffic in PHP?

To limit CURL traffic in PHP, you can set the maximum number of connections allowed using the CURLOPT_MAXCONNECTS option in CURL. This will prevent your PHP script from making too many simultaneous connections, which can help prevent server overload and improve performance.

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com');
curl_setopt($ch, CURLOPT_MAXCONNECTS, 5); // Set maximum number of connections to 5
$response = curl_exec($ch);
curl_close($ch);
