How can developers ensure access to reliable and functioning PHP resources?

Developers can ensure access to reliable and functioning PHP resources by properly handling errors and exceptions, implementing robust error handling mechanisms, and regularly monitoring and maintaining their PHP code. It is essential to use try-catch blocks to catch and handle exceptions gracefully, log errors for debugging purposes, and utilize PHP's built-in functions for error handling and reporting. 

try {
    // PHP code that may throw exceptions
} catch (Exception $e) {
    // Handle the exception, log error messages, and gracefully recover
    echo 'Caught exception: ' . $e->getMessage();
}
