How can proper error handling be implemented in the PHP code to address potential issues?

Proper error handling in PHP can be implemented by using try-catch blocks to catch exceptions and handle errors gracefully. By wrapping potentially problematic code in a try block and using catch blocks to handle specific exceptions, you can prevent your application from crashing and provide meaningful error messages to users.

try {
    // Code that may throw an exception
    $result = 1 / 0;
} catch (Exception $e) {
    // Handle the exception
    echo "An error occurred: " . $e->getMessage();
}
