How can PHP developers optimize the use of cURL for server-side pinging in PHP applications?

To optimize the use of cURL for server-side pinging in PHP applications, developers can reuse cURL handles instead of creating a new handle for each request. This can help improve performance by reducing the overhead of creating and destroying cURL handles repeatedly.

// Initialize cURL handle
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'https://example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute cURL request
$response = curl_exec($ch);

// Close cURL handle
curl_close($ch);
