Hi.. I've got a short Perl question... I want to take the contents of a variable called, say, $input 
$input = "word+word+word";

[download]
and split it up, so that i can put something along the lines of the following into a variable, which we'll call $string 
keyword1=word&keyword2=word&keyword3=word

[download]
I've drawn up some mock Perl code to help give a better idea of what i mean. 
$string = "";
$wordnum = 0;
$input = "word+word+word";
(@keywords) = split(/\+/, $input);

foreach $keyword (@keywords){
$wordnum++;
$string .= qq~keyword_$wordnum=$keyword~;
}
