How can error handling and logging be improved in PHP scripts to identify and troubleshoot issues like sporadic job failures?

Sporadic job failures in PHP scripts can be difficult to troubleshoot without proper error handling and logging. To improve this, you can implement a robust error handling system that logs errors to a file or database, allowing you to track down the root cause of the failures more easily. 

// Set error handling to log errors to a file
ini_set('error_log', 'error.log');
ini_set('log_errors', true);

// Custom error handler function
function customErrorHandler($errno, $errstr, $errfile, $errline) {
    error_log("Error: [$errno] $errstr in $errfile on line $errline");
}

// Set the custom error handler
set_error_handler("customErrorHandler");

// Example code that may encounter sporadic failures
try {
    // Your PHP script code here
} catch (Exception $e) {
    error_log("Exception caught: " . $e->getMessage());
}
