F5 detects PHP Deprecated.

Ian Hi,

We are seeing PHP logs on the webserver itself.

Now we wonder why the logs are came from f5.

Please see logs sample:

[Tue May 17 09:53:54 2016] [error] [client 10.10.10.210] PHP Deprecated: Function set_magic_quotes_runtime() is deprecated in /var/www/html/forum/common.php on line 106 [Tue May 17 09:53:54 2016] [error] [client 10.10.10.210] PHP Deprecated: Function ereg_replace() is deprecated in /var/www/html/forum/portal/includes/mini_cal/mini_cal_common.php on line 82 [Tue May 17 09:53:54 2016] [error] [client 10.10.10.210] PHP Deprecated: Function ereg_replace() is deprecated in /var/www/html/forum/portal/includes/mini_cal/mini_cal_common.php on line 82 [Tue May 17 09:54:01 2016] [error] [client 10.10.10.210] PHP Deprecated: Function set_magic_quotes_runtime() is deprecated in /var/www/html/forum/common.php on line 106 [Tue May 17 09:54:02 2016] [error] [client 10.10.10.210] PHP Deprecated: Function ereg_replace() is deprecated in /var/www/html/forum/portal/includes/mini_cal/mini_cal_common.php on line 82 [Tue May 17 09:54:02 2016] [error] [client 10.10.10.210] PHP Deprecated: Function ereg_replace() is deprecated in /var/www/html/forum/portal/includes/mini_cal/mini_cal_common.php on line 82

10.10.10.210 is the f5 selfIP. We just wanted to know why f5 detects this kind of logs even though it is related on the application side/coding

Thanks
