How can the use of @ in PHP code affect error handling and what are the alternatives?

Using "@" in PHP code suppresses error messages, making it difficult to debug and troubleshoot issues in the code. Instead of using "@" to suppress errors, a better approach is to handle errors using try-catch blocks or error handling functions like set_error_handler(). 

// Using try-catch block to handle errors
try {
    // code that may throw an error
} catch (Exception $e) {
    // handle the error
    echo "An error occurred: " . $e->getMessage();
}

// Using set_error_handler() to customize error handling
function customError($errno, $errstr, $errfile, $errline) {
    echo "Error: [$errno] $errstr - $errfile:$errline";
}

set_error_handler("customError");
