Well, I'm off to the Vancouver Users' Conference to give a few talks. A bunch of us PHP guys will be there, and it looks like it will be a good time.

While I'm there, I'll be presenting a BoF (Birds of a Feather) session where I'll introduce my new project -- the philter extension. That's all I'm going to say for now, but I think you'll like what I have brewing so if you're going to be at the conference stop by and visit the BoF.

Today I got an e-mail from someone random trying to get me to sign on their search engine (or some sort of search-engine registering service)... I was just about to delete the mail, when I noticed this:



This is the most entertaining thing I've ever seen in spam in a long time. I have no idea if they've found some sort of method of automating this sort of graphic generation, but it's pretty darn funny if you ask me :)

Note: In the original e-mail it looked a little better, the Y-axis was "Search Engine Listings" and the X-axis was "Unique Visitors".. Everything was also really clean so you couldn't even tell that the screenshot was a background image/layer

My new e-mail signature...


<?php for(${chr(0x5F)}=chr(0x61),${0x0}=0x61,${0x2A}=0;${0x0}!=0x7B;${0x0}++)${
chr(0xD)}[(${0x2A}++)]=chr(${0x0});${(${${_}}=rand(0x0,0xFF))}=

hexdec(${$a}[${0x0}].${$a}[${0x0}+1]);@${$z}.=(${0x32}>0x19)?chr(${0x32}):${
chr(0xD)}[${0x32}];++${0x0};}echo "{${""}}\n"?>



Perhaps I should start an obfuscated php contest :)

I don't know about PHP 4.3.x (I haven't tested).. but in PHP 5 the following script is completely valid:


<?php

    class weird {

          var $myvar;
    
          function __construct() {

            $myvar = "Z";
            $this->myvar = "A";
            $this->$myvar = "B";
            $this->${'myvar'} = "C";
            $this->${'$myvar'} = "D";

            echo 'this->myvar: '.$this->myvar."\n";
            echo 'this->$myvar: '.$this->$myvar."\n";
            echo 'this->${\'myvar\'}: '.$this->${'myvar'}."\n";
            echo 'this->${\'$myvar\'}: '.$this->${'$myvar'}."\n";
            echo 'this->$$$$$$$myvar: '.$this->$$$$$$$myvar."\n";
            echo 'this->$$$$$$${\'$$$myvar\'}: '.$this->$$$$$$${'$$$myvar'}."\n";                    
         }
    }

    new weird();
?>




Not only is it valid, but the output is also interesting:


this->myvar: A
this->$myvar: C
this->${'myvar'}: C
this->${'$myvar'}: D
this->$$$$$$$myvar: D
this->$$$$$$${'$$$myvar'}: D



If you remove the declaration of the local $myvar in the constructor you get:


this->myvar: A
this->$myvar: D
this->${'myvar'}: D
this->${'$myvar'}: D
this->$$$$$$$myvar: D
this->$$$$$$${'$$$myvar'}: D


I don't *think* this is a bug, from what I understand of the way the engine works. However, it is quite odd isn't it? Here's something that's even more interesting -- did you know you *can* define a variable that starts with a
number?


<?php
    ${1} = "Hi";
    echo "${1}\n";
?>




In fact, you can put just about any expression you want in between the ${ } and create a variable (including NULL). Of course, it is strongly recommended you EVER do such things in a real PHP script -- I just thought I'd share.

it seems like it was just last week I was in Germany for the International PHP Conference. However, I just got word that I'll be taking another trip to Europe for the International PHP Conference, Spring Edition in Amsterdam. I'll be giving two talks, one on Smarty and the other one (you guessed it) on the new tidy extension in PHP 5.0

And here I thought I was going to have some time off from travel :)

Today I was told on IRC by one of the organizers for the PHP Quebec Conference that I've been invited to come and give a session on my Tidy extension! Of course I plan on going, its March 25th and 26th so if you'd like to go you better hurry up and register!

See you in Montreal!

For the longest time I have been lurking on the Chicago User Group's mailing list since its really the only user group close to me. I haven't ever really been into the user group thing in the past, but today I had an opportunity to be their Guest Speaker for this month's meeting! Being a user-group virgin, I didn't really know what to expect -- so I was happy to find them all a great group of PHP-interested folks. They paid attention during my talk, asked a lot of questions (a lot more then in more formal talks I've given), and we all learned a thing or two!

If you live in the Chicagoland area and weren't at the meeting this month you missed out on a great time. For those interested in getting involved with the Chicago user group their web site is http://chiphpug.php.net/. Apparently it is having problems right now due to some unrelated php.net changes but I'm sure it'll be up soon.

Oh, and in case you were curious I gave a talk on Tidy version 2.0. It will be available at talks.php.net as soon as the server syncs with CVS.

Thanks for having me gentlemen -- it was a great time.
