debugger has stopped evaluating $this

to test this I can add a line in a class method that reads

$a = $this->stockType

break after that line and evaluate $a using the immediate window and I get..

$a
: string = Tube

which is correct but when using the $this keyword in the immediate window I get..

$this->stockType
: Error -- Error: E_ERROR (Using $this when not in object context)

it's

PHP Version: 5.1.6
Web Server: Apache/2.2.3 (Red Hat)
Platform: Linux-glibc-2.5/x86_64

with most up to date versions of PhpEd (17027, 64 bit)
DBG (PHP DEBUGGER) Version 8.1.6

thanks

First of all, dbg 8.1.6 is outdated. You need to update it. Then check what you have in Watches window. Statements like unset($this) or $this=NULL would definitely make render $this undefined. Check if you have conditional breakpoints with similar things. Try to cleanup Watches and Breakpoints, and reproduce with very very simple script.

Hi dmitri,

thanks for the response - I've updated the debugger to 8.1.9 now, cleared all breakpoints, watches etc and tested with a very simple script to demonstrate the problem.

Your code works fine in PhpED:

It's hard to guess what should be done to screw up php so it wouldn't work.
Can you show phpinfo()?

I'd also suggest using a different version of PHP. Version 5.1.6 is way too old and was end of life in Aug-2006.

I have myself seen strange debugger issues that were specific to PHP versions. Not saying that's the case, but worth a try.

Switching to higher version may help, but php-5.1.6 is still supported as well as all php versions starting with 4.3, with a very few minor exceptions, like completely broken php-5.2.0 (required minimum is 5.2.3) or php-5.0.0 (required minimum is 5.0.5). Php-5.1.6 under redhat linux should work and I'll check this. Stay tuned.

problem is reproduced and fixed in dbg-8.1.11. Update is on its way to web site.
