PHP References Article
The June 2005 issue of php|architect published an article on "References in PHP". The article explains in detail how variables exactly work in PHP, in a hopefully clear text and with diagrams.
The magazine kindly allowed me to publish a PDF of this article on my site so that it can reach a greater audience. You can find the PDF here .

That's a little freaky - in Firefox on my system, it starts to load, then jumps over to the php|a page talking about the print edition...
It seems that the whole image on the first page has an HTML link to that page... Just don't click on it and you will be fine :)
It's pretty hard to get ones hands on internal architecture documentation when usage documentation is so abundent.
Thank you!
What good is it to have a tool and not know what it does. So many PHP books I have read skip on the important technical parts. Thank you Derick for helping me to understand PHP references.
Cheers!

Curlew on the Grass
This was one of several Curlews we saw, but this one was vaguely camouflaged in the colourful heather.

For one of Xdebug's features (native path mapping), I currently support line mapping as in:
```
user-info-823edfe12e38a.php:2-31 = user-info.ezt:1
user-info-823edfe12e38a:32-33 = user-info.ezt:2
…
user-info-823edfe12e38a:303 = user-info.ezt:74-75
```But this is not an efficient format.
I wonder if somebody else has a better idea than I have in https://bugs.xdebug.org/view.php?id=2400:
```
user-info-823edfe12e38a.php = user-info.ezt (@2-31=1;32-33=2;…;303=74-75)
```Specify bridge structures
Specify width of opening
Survey if places still exist
Survey if vacant places are still vacant
Survey opening hours
Specify whether traffic signals have tactile indications that it's safe to cross
Specify whether roads have lane markings
Specify whether there are cycleways
Survey postbox collection times

Dartford Warbler Posing
In nearly the same spot as the Stonechat from the previous post, this tiny Dartford Warbler sat still here for a few moments.
