RE: [PHP] Found a PHP bug!!!!!!!!!

Scott, Because "8" != 8. "8" (and "08") is a string with the numerals representing the number eight. It is not the number eight. (think back to basic math, the difference between a number and a numeral) PHP does some conversions for you automatically but that just saves you from yourself. (Personally, I wish it wouldn't. People have more trouble *because* of the automatic conversions than they would if they had to do the converting themselves.) To keep from running into this simply do the conversions yourself before you do comparisons. intval("08")==8 =C= * * Cal Evans * Stay plugged into your audience. * http://www.christianperformer.com * -----Original Message----- From: Scott Fletcher [mailto:scott@abcoa.com] Sent: Monday, January 27, 2003 2:14 PM To: php-general@lists.php.net Subject: Re: [PHP] Found a PHP bug!!!!!!!!! I don't see why a string wouldn't work when I use "08" (string) and match it against the integer 8, or 08.
