Dear all, A few things I can't figure out - the first, what does the following mean? I see it crop up in Form Validation scripts all the time, but can't seem to find anywhere that explains it properly. It's in the script I've bent to my own uses, but even if I comment it out, the script seems to run properly. Hrm.

$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;

Secondly, and more importantly, how would I begin to write a function to count the number of times a specific word appears on a page. For example - a search box, returning "Your search for $keyword returned X number of results on the page". Can't seem to fathom it.

I assume that if (/$keyword/i) would only find the first occurance of the word on the page? Note: I have the search/output all working, it's just counting the number of times the $keyword is present that's got me stumped.

Just don't know enough about this perl thing :)

Many thanks,

NL.
