What are the security implications of using links to manipulate files in PHP?

Using links to manipulate files in PHP can pose a security risk as it opens up the possibility of allowing malicious users to access, modify, or delete sensitive files on the server. To prevent this, it is important to validate user input and sanitize any file paths before using them in file manipulation functions. 

// Sanitize file path before using it for file manipulation
$filePath = 'path/to/files/' . basename($_GET['file']);

if (file_exists($filePath)) {
    // Perform file manipulation operations here
} else {
    echo 'File not found';
}
