Welcome to the third part of an eight-part series on building loader applications in PHP. In the tutorials that comprise this series you’ll find numerous examples aimed at demonstrating how to create small, yet efficient, resource loader classes, not only by taking advantage of PHP includes, but the handy “__autoload()” magic function and the Standard PHP Library (SPL) as well.
PHP makes life a lot easier for quick or dirty maintenance scripts, cron jobs or web applications but how does it do for older, not so straight forward problems dealing with bits and bytes? I was surprised how easy it was to manipulate bits in a byte with php. Here is an function that made my life a fair amount easier when having to check for a specific bit in a byte.
This function checks whether a certain bit is set or not given a byte and an index.
Magic functions are an important part of the numerous improvements and additions that were introduced originally in PHP 5. They can be extremely handy when it comes to simplifying the execution of complex tasks. This is the fourth part of a seven-part series that showcases some of the more useful magic functions and how to implement them.
Welcome to the fourth chapter of the series that shows you how to build loader applications with PHP. Made up of seven parts, this series uses a variety of code samples to teach you how to create modular programs. These programs are capable of recursively including files required by a given application, without having to explicitly call any “include()/include_once()” or “require()/require_once()” PHP function.
If you’re a PHP developer who wishes to learn how to implement and use the set of magic functions that come included with PHP 5, you’ve come to the right place. Welcome to the third part of a series that takes a close look at magic functions in PHP 5. Made up of seven tutorials, this series teaches you how to work with the most common PHP 5 magic functions, putting particular emphasis on their usage within the context of object-oriented applications.
Spam is one of the biggest problems on the Internet. It is getting harder to fight with the advent of spam bots that visit websites and automatically fetch email addresses, fill out forms and do other nasty things, such as blog spam comments, that could degrade your integrity. Fortunately, using captcha can help. This article will show you how to implement captcha on your site.
If you’re a PHP developer who has already worked with popular third-party frameworks like Kohana and CodeIgniter, or even better, have created one all by yourself, then you're familiar with building file loading applications. The process can be tackled pretty easily, either by using a procedural approach or the object-oriented paradigm. In this eight-part series, we take a close look at building file-loading applications. This second part of the series will focus on static methods.
Welcome to the second part of a seven-part series on the magic functions in PHP 5. In the previous article, we looked at property overloading with the get and set functions. In this one, we'll take a look at the same task using the isset and unset magic functions.
The ability to encrypt and safeguard data is an essential ability that every serious web developer should have in their arsenal. In this article we'll explore encrypting data with PHP and MCrypt (libmcrypt), storing it in a database, retrieving it from a database and decrypting it for use.
When trying to maintain a secure protocol on an Apache-based website, you can expect to deal with certain issues, especially if you're also trying to rank well in the search engines. This article provides you with some solutions for two of the more difficult problems: duplicate content and 301 redirects.
