How can time-related issues impact the functionality of PHP scripts that check server availability?

Time-related issues can impact the functionality of PHP scripts that check server availability if the script relies on timeouts or delays that are too short or too long. To solve this issue, it's important to set appropriate timeout values for network requests and ensure that the script handles delays effectively to prevent timeouts. 

// Set timeout values for network requests
$timeout = 10; // Timeout in seconds

// Create a cURL handle
$ch = curl_init();

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

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

// Check for errors
if(curl_errno($ch)){
    echo 'Error: ' . curl_error($ch);
}

// Close cURL handle
curl_close($ch);

// Process the response
echo $response;
