 * Hi, concerning BBQ Firewall, my php checker says:
 *     ```
       FOUND 3 ERRORS AFFECTING 3 LINES
       ------------------------------------------------------------------------------------------------------------------------------------------------------
        47 | ERROR | The behaviour of hexadecimal numeric strings was inconsistent prior to PHP 7 and support has been removed in PHP 7. Found: '0x00'
        49 | ERROR | The behaviour of hexadecimal numeric strings was inconsistent prior to PHP 7 and support has been removed in PHP 7. Found: '0x3c62723e'
        51 | ERROR | The behaviour of hexadecimal numeric strings was inconsistent prior to PHP 7 and support has been removed in PHP 7. Found: '0x00'
       ------------------------------------------------------------------------------------------------------------------------------------------------------
       ```
   
 * I seached the support forum and read that it is safe to ignore such information.
   Is it correct? I would like to update my php version. Thanks for confirmation
   that I can safely ignore these three lines.
 * Best regards, Nina

 * Yep, those are hard-coded literal strings, they are not processed by PHP as actual
   code. So false positives and totally safe to ignore. And you may even want to
   mention to your PHP/scan provider, so they can try to improve the quality of 
   their plugin.
