What are some best practices for error handling and debugging in PHP?

Issue: Error handling and debugging are crucial aspects of PHP development to ensure code stability and identify issues quickly. Best practice for error handling in PHP is to use try-catch blocks to catch exceptions and handle errors gracefully. Additionally, enabling error reporting and logging errors to a file can help in debugging. Using tools like Xdebug for step-by-step debugging and profiling can also aid in identifying and fixing issues efficiently. 

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

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

// Use try-catch blocks for exception handling
try {
    // Your PHP code here
} catch (Exception $e) {
    error_log("Exception: " . $e->getMessage());
}

// Debugging with Xdebug
// Install Xdebug extension and configure IDE for debugging
