What common mistakes are made when using fsockopen in PHP for server testing?

One common mistake when using fsockopen in PHP for server testing is not properly handling errors and timeouts. It's important to check for errors and timeouts to ensure the connection is successful. Additionally, not closing the socket after the connection is made can lead to resource leaks. 

$host = 'example.com';
$port = 80;

$socket = fsockopen($host, $port, $errno, $errstr, 10);

if (!$socket) {
    echo "Error: $errstr ($errno)";
} else {
    // Connection successful, do something with the socket

    fclose($socket); // Close the socket after using it
}
