Hi,
Avoid the foreach, because is will impact the performance, instead use a preg_match().
Take a look here https://gist.github.com/Exadra37/9453909
In line 6, you forgot a bracket. ;)
Nice
is there any option to detect bad bots ?
I am running a website, I get thousands of spammers on my website : www.funkodia.com
