PHP: simple captcha script
posted in PHP on 2013-08-08 array, code, expression -
In my company, we have a lot of WordPress sites. Some of them require contact form with captcha field. The short way for solving such task is to use a plugin. However, as you may guess, the add-ons are available for everyone, which means that they could be easily explored and probably hacked. That's why I suggested a simple, custom script, which is developed by us.

mod_rewrite, one simple rule and two stupidly lost hours
posted in PHP on 2013-06-05 public, favicon png, index php -
Ok, I should admit that mod_rewrite and regular expressions are not my strongest part. Today - as every other day I realize how little knowledge I have. Actually it's good to have such moments. I lost almost two hours fighting with a really really simple mod_rewrite rule in my .htaccess file. read more comments

PHP developers - wake up!
posted in PHP on 2013-01-16 code, time, things - PHP is one of the most popular back-end solutions available. However, I think that there is something wrong with the way we are using it. It is really popular to use some giant framework, with a lot of features. Generally, I'm not a big fan of this approach. Even if the framework is well documented and has big community it still adds some restrictions and complexity. Many people are trying to build the perfect framework, which covers as many cases as possible, but the true is that it is not possible. In this article I'll present you my vision about PHP programming and I will be very happy if you share yours. read more comments

Dependency Injection in PHP. Create your own DI container.
posted in PHP on 2012-05-12 class, key, view - By my opinion one of the biggest problems in programming are dependencies. If you want to have a good well written application you should avoid dependencies between your modules/classes. There is a design pattern which could help and it's called Dependency Injection (DI). It allows you to inject objects into a class, instead of creating them there. read more comments

Basic PHP authentication
posted in PHP on 2011-10-17 php_auth_pw, php_auth_user, password - The .htaccess file is actually a possible solution for this purpose. The problem with this approach is that the value of AuthUserFile should contain an absolute path. It also works with relative paths, but it is relative based on ServerRoot, which in most of the cases is different from DocumentRoot. I also didn't want to deal with sessions or cookies and after a short research I found the answer. read more comments

Export mysql data to SQL script or CSV
posted in PHP on 2010-09-04 server, data, mysql - Yesterday I received host name, user name and password for a MySQL server. I needed to export the data from it. I didn't have access to PHPMyAdmin, I tried to connect to the server by mysql.exe on my PC, but it didn't work. And then I found really good solution - PHPMyAdmin in only one php file. I launched it from my localhost and it works. So if you need to export data or just see it, use Adminer. I also uploaded the file on my server, you can download it from here. read more comments
