What is the significance of using @$suche = @$_REQUEST["suche"]; in PHP programming?

When using $_REQUEST to retrieve user input in PHP, it is important to sanitize and validate the input to prevent security vulnerabilities such as SQL injection attacks. By assigning the input value to a new variable like $suche and using the @ symbol to suppress any error messages, we can handle potential errors more gracefully and securely.

$suche = @$_REQUEST["suche"];
// Use $suche variable in your code after sanitizing and validating it
