What is the purpose of the One-Use-Link-Script on the website?

The One-Use-Link-Script on the website is used to generate unique, one-time use links for specific actions or resources. This is typically done to enhance security and prevent unauthorized access or sharing of sensitive information. Each time a user accesses the link, it is marked as used and cannot be accessed again. 

// Generate a unique, one-time use link
$unique_link = md5(uniqid(rand(), true));

// Store the link in a database or session for validation
$_SESSION['one_time_links'][] = $unique_link;

// Validate the link when it is accessed
if(in_array($_GET['link'], $_SESSION['one_time_links'])) {
    // Link is valid, perform action
    // Remove the link from the list to prevent reuse
    unset($_SESSION['one_time_links'][array_search($_GET['link'], $_SESSION['one_time_links')]);
} else {
    // Link is invalid, display an error message
    echo "Invalid link";
}
