5.3.1 is what we call 'current release'. for those who do not like to
sit on the edge, the latest is 5.2.12.
both get bug fixes (checkout the home page release announcements), so
they are 'still supported'. that means those versions earlier to
5.2.11 do not get bug fixes hence 'not supported but stable'

PHP5.3 introduced a number of 'improvements' that require many third party
packages to be re-worked. Something which has still to be completed in many
cases. In addition a number of key parts are not now available in Windows builds
of PHP5.3, so many of us do not have the option as yet to switch TO the 5.3
branch in production. Until PHP5.3 is fully supported and complete, 5.2 still
needs to be maintained!

And that was supposed to have gone to the list as well. Sorry. Hit the
wrong button.

I was dealing with large & deep arrays in PHP and wanted a better way to
view such data structures in the browser.
So i've built a few functions that show such structures initially collapsed,
with various options to click-and-see what's in a sub-value.
It can also handle HTML within JSON, and JSON within JSON.
Dumping an array from PHP is as simple as
htmlDump ($arr, $title);
For a demo & download (LGPL) see http://skatescene.biz/jsonDebug-1.0.0/
If you have any improvements, please let me know; rene7...@gmail.com

Hi all. Perhaps a lazy request, but does anybody have some cut-n-paste code to
calculate a Luhn check-digit?
It's a check-digit often added to the end of things like credit card or account
numbers to make detecting typo's a bit easier.
I found lots of code to validate a number once the check-digit is applied, but
nothing to calculate the digit in the first place.
Thanks in advance !

And that 20 is a typo. Sorry.

Hi all, first time I have posted here so please be nice.
I am using PEAR HTTP_Upload to handle multiple file uploads. What I need to do
is to take the file name which is output using the getProp() function and then
remove the file extension from the end of the file for example:
Original name held in the getProp() array [name] "word_doccument.docx"
I need to put this into a string such as
$filename = $props['name'];
I then need to separate the file name from the file extension.
I have been reading the php manual do please don't bother referring me to that.
Thanks in advance.

There are a couple of ways you could do this. The most straightforward
way would be to use the pathinfo() function.
<?php
$file = 'word_document.docx';
$extension = pathinfo($file, PATHINFO_EXTENSION);
$name = pathinfo($file, PATHINFO_FILENAME);
?>
See http://php.net/pathinfo for more information about that function.
You could also explode() it and do something with that, or you could
or use some of the other many string manipulation functions. I think
pathinfo() is easiest.

PHPBB uses the substr() function along with the strrpos() function to
grab the extension from a file. You could do something like this:
(untested - I always forget the order of the params!)
$name = substr($filename, 0, strrpos($filename, '.'));

As a general rule, string functions are always haystack-needle and
array functions are always needle-haystack. I can't think of any
exceptions to that rule.
