What are some best practices for efficiently managing an array of hosts to contact in a PHP application?

When managing an array of hosts to contact in a PHP application, it is important to efficiently handle the connections to these hosts to avoid performance issues. One best practice is to use a loop to iterate through the array of hosts and make asynchronous requests to each host to avoid blocking the application while waiting for responses. Additionally, consider implementing connection pooling to reuse connections and reduce overhead. 

// Array of hosts to contact
$hosts = ['host1.com', 'host2.com', 'host3.com'];

// Loop through the array of hosts and make asynchronous requests
foreach ($hosts as $host) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $host);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    // Add additional curl options as needed
    $multi_handles[] = $ch;
}

$mh = curl_multi_init();

foreach ($multi_handles as $ch) {
    curl_multi_add_handle($mh, $ch);
}

$active = null;
do {
    $mrc = curl_multi_exec($mh, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);

while ($active && $mrc == CURLM_OK) {
    if (curl_multi_select($mh) != -1) {
        do {
            $mrc = curl_multi_exec($mh, $active);
        } while ($mrc == CURLM_CALL_MULTI_PERFORM);
    }
}

foreach ($multi_handles as $ch) {
    // Process the response for each host
    $response = curl_multi_getcontent($ch);
    // Do something with the response
}

foreach ($multi_handles as $ch) {
    curl_multi_remove_handle($mh, $ch);
    curl_close($ch);
}

curl_multi_close($mh);
