What are some strategies for improving error handling and troubleshooting in PHP applications?

Issue: Improving error handling and troubleshooting in PHP applications can be achieved by setting error reporting levels, using try-catch blocks for exception handling, and logging errors to a file for easier debugging. Code snippet: 

// Set error reporting level to catch and display all errors
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Use try-catch block for exception handling
try {
    // Code that may throw an exception
} catch (Exception $e) {
    // Handle the exception
    echo 'Caught exception: ' . $e->getMessage();
}

// Log errors to a file for troubleshooting
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');
