What is the purpose of using "@" in PHP code and why should it be avoided?

Using "@" in PHP code suppresses error messages, which can make debugging more difficult as it hides potential issues in the code. It is generally considered a bad practice because it can lead to unexpected behavior and make it harder to troubleshoot problems. Instead of using "@" to suppress errors, it is recommended to handle errors properly using try-catch blocks or error handling functions. 

// Bad practice: using "@" to suppress errors
@$result = 1 / 0;

// Good practice: handling errors using try-catch block
try {
    $result = 1 / 0;
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
