From: Operating system: Linux Debian 5 'Lenny' PHP version: 5.2.17 Package: Scripting Engine problem Bug Type: Bug Bug description:Parsing bug if a pattern looking like closing ASP tag appears in comment
Description: ------------ A parsing error occurs if a pattern looking like a closing ASP tag appears inside a line comment (beginning by '//'), in a PHP engine having 'asp_tags = On' in the 'php.ini' file. If I remove the "//" comment, I have a big "Line 2" visible, and there is no bug. If I use a "/* */" style comment instead, there is no bug. If I put quotes around "140%" in the "size" attribute, there is no bug. If I set the "asp_tags" options to "Off", or if I remove it, there is no bug. Removing the 'if' condition around the comment results in another kind of problem (no error, but part of HTML code visible). I found this because I was trying to install the latest version of OCS Inventory (http://www.ocsinventory-ng.org/), and I didn't understand why I got a white page and a PHP parse error after the first step of installation: I have 'asp_tags = On' in 'php.ini', and there is effectively a commented out '%>' pattern in their code. Looks like a little to Bug #4879 (more than 10 years old).
