How can the PHP code be optimized to update the 'download_defekt' column in the database for unreachable links?

To optimize the PHP code for updating the 'download_defekt' column in the database for unreachable links, we can use a loop to iterate through the list of links and check their status using functions like cURL or file_get_contents. If a link is unreachable, we can update the 'download_defekt' column for that specific link in the database.

<?php
// Assuming $unreachable_links is an array of unreachable links
foreach($unreachable_links as $link) {
    $status = checkLinkStatus($link); // Function to check link status using cURL or file_get_contents

    if($status === false) {
        // Update 'download_defekt' column in the database for the unreachable link
        $query = "UPDATE your_table SET download_defekt = 1 WHERE link = '$link'";
        // Execute the query using your database connection
    }
}

function checkLinkStatus($link) {
    // Implement code to check link status using cURL or file_get_contents
}
?>
