What are the potential issues with using import_request_variables in PHP scripts?

Using import_request_variables in PHP scripts can lead to security vulnerabilities such as injection attacks and variable overwrite issues. It is recommended to avoid using this function and instead use superglobals like $_GET, $_POST, and $_REQUEST to access request variables. 

// Avoid using import_request_variables
