Alex Inführ:
PHP non alpha numeric 7 and 6 char code
December 17, 2012 @ 09:32:02

Following along with the non-alpha PHP code that Gareth Heyes recently posted about, Alex Inführ has created some of his own using only dollar signs, underscores, equals, plus and parentheses.

I used the following charset: $_=+(); As you can see only 7 chars. In the end the function log will be created,because this won't exceed the memory limit. In the beginning I created the php function assert and it was 99 mb large php file, way too big to get executed.

He uses a few tricks to get the language to create strings (counting to infinity), changing the letters in the resulting string, He includes the steps in the process and a large block of the non-alpha PHP code at the end of the post, a 46KByte block that echoes "log(12)".

IBM developerWorks:
Build seven good object-oriented habits in PHP
October 31, 2008 @ 07:51:59

The IBM developerWorks website has a few suggestions - seven of them, in fact - that they think can help make you a better PHP programmer.

With PHP's object-oriented (OO) language features, if you aren't already creating your applications with OO principles in mind, these seven habits will help you get started in the transition between procedural programming and OO programming.

Each of the seven OOP habits have more details below them, but here's the short list:

  • Be modest.
  • Be a good neighbor.
  • Avoid looking at Medusa.
  • Embrace the weakest link.
  • You're rubber; I'm glue.
  • Keep it in the family.
  • Think in patterns.

In each there's a "bad habit" and a "good habit" to explain the concept a bit more fully, everything from error handling to interfaces.

Sara Golemon's Blog:
PHP4 turns 7 years old today
May 22, 2007 @ 09:27:00

As Sara Golemon points out on her blog today, it's the 7th birthday of the very first release of PHP4:

Check the official releases page for yourself. PHP 4.0.0 was released seven years ago today. Make a cake, blow out some candles, and put on your birthday suit (no not that one); Now give that brat a kick out the door, he's been loafing around on your server for too long.

Of course, if you're still stuck in the PHP4 days, there's the latest - PHP 4.4.7 - or, if you're ready to join the rest of the world, PHP 5.2.2.

Kore Nordman's Blog:
Raytracing with Image_3D
April 05, 2006 @ 07:48:36

Kore Nordman has been making even further advancements in the development behind the PEAR Image_3D library - this time, he looks at raytracing in PHP.

I was always writing, that implementing a raytracer (or the better german description) in PHP would be far to slow. And then, two days ago, I had the feeling I should prove this ... this was also the way Image_3D was born. With the infrastructure Image_3D offers, all the existing models, the abstraction etc. it wasn't such a big thing. You mainly need to write a short algorithm which gets the intersection point for a polygon with a line, and that's it. For sure, you should optimze the algorithm a bit. And it is really fun to implement such a simple mathematical model like raytracing is.

He talks about some of the problems that raytracers don't have that normal renderers do (shadows, reflections, etc) and notes that the images display in the post took about seven minutes to render on his system. He proved that it can work, but notes that it supports his original hypothesis - rendering like this with PHP is just too slow.

John Cox's Blog:
Security Blunders
December 21, 2005 @ 07:08:07

In his latest post today, John Cox takes a look at one of the latest posts from the SitePoint PHP blog - the Top 7 PHP Security Blunders.

This morning I read the Top 7 PHP Security Blunders which contained (at least in my mind) a few questionable comments about PHP security. Luckily for the early readers of the article, there was a very long comment by comments were a very nice critique of the article which also corrects a few obvious mistakes within the article itself.

The comments have now been pushed off the main article to the forum, (which is a shame) but as a developer, you would be doing yourself a disservice by not also taking the time to read the counter-point. They are insightful without being inflammatory.

The comments by Chris that he makes reference to can be found here in the SitePoint forums...

Top 7 PHP Security Blunders
December 21, 2005 @ 07:04:07

On the SitePoint PHP blog today, Pax Dickinson shares with us the "Top 7 PHP Security Blunders" as he sees them.

In this article, I'll detail many of the common PHP programming mistakes that can result in security holes. By showing you what not to do, and how each particular flaw can be exploited, I hope that you'll understand not just how to avoid these particular mistakes, but also why they result in security vulnerabilities. Understanding each possible flaw will help you avoid making the same mistakes in your PHP applications.

His list includes:

  • Unvalidated Input Errors
  • Access Control Flaws
  • Cross Site Scripting (XSS) Flaws
  • Data Handling Errors

There's more listed, so be sure to check out the rest of the article - each item is explained and on some, sample code is included where it makes sense...
