This returns 000, it should return 743 "Analysis & Solutions" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > On Tue, Jul 02, 2002 at 10:19:59PM -0400, Greg Wineman wrote: > > > > He are the variables from my form > > > > wins_1=7 > > losses_1=0 > > sort_1=1 > > wins_2=7 > > losses_2=4 > > sort_2=2 > > wins_3=7 > > losses_3=4 > > sort_3=3 > > > > $counter=1; > > $wins=eval("\$wins_".$counter); > > eval() is overkill and can be dangerous. > > I'd use variable variables instead: > > $wins = 0; > for ($counter=1; $counter<=3; $counter++) { >$var = "$wins_$counter"; >$wins = $wins + $$var; > } > > --Dan > > -- >PHP classes that make web design easier > SQL Solution | Layout Solution | Form Solution > sqlsolution.info | layoutsolution.info | formsolution.info > T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y > 4015 7 Av #4AJ, Brooklyn NY v: 718-854-0335 f: 718-854-0409 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] eval problem
Hello, Could someone offer some insight on eval(); I am fairly new at this. I would like to evaluate numerous variables from a form submission with a loop, but I can;t even get on to work: I.e. He are the variables from my form wins_1=7 losses_1=0 sort_1=1 wins_2=7 losses_2=4 sort_2=2 wins_3=7 losses_3=4 sort_3=3 I am trying to evaluate the values based on a loop. Here's my current method $counter=1; $wins=eval("\$wins_".$counter); $wins should return 7 in this example. Where am I going wrong? Any help would be appreciated.
