How can server latency or high-latency routes impact the functionality of cURL_exec() in PHP, and what steps can be taken to address this issue?

Server latency or high-latency routes can impact the functionality of cURL_exec() in PHP by causing delays in retrieving data from external servers. To address this issue, one can set a timeout value for cURL requests to prevent the script from waiting indefinitely for a response. 

// Set a timeout value for cURL requests
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10); // Set timeout to 10 seconds

$response = curl_exec($ch);

if($response === false){
    echo 'cURL error: ' . curl_error($ch);
}

curl_close($ch);
