Installing PHP 5.2.10-Win32 on Windows7 32 bit is practically the same as Vista,but I had few people asking me how to do it,so I wrote a new Tutorial, and I tested all the steps on a 32bit version,so far.Read the article,it's very easy

This tutorial will demonstrate how to resize images with PHP. The ability to resize images is useful for creating thumbnails for image galleries.

This tutorial will demonstrate how to use PHP to perform a redirect. The PHP header function will be used to send the HTTP headers required to perform the redirect.

This tutorial will demonstrate how to use arrays in PHP, with code examples of all fundamental array operations.

This tutorial covers the basics of accessing a MySQL database from your PHP script. You will learn how to connect to a MySQL database, and how to execute a SQL statement. The example code will output an HTML table containing the contents of a table in the database.

Having trouble making the leap from procedural to object-oriented programming (OOP)? In this tutorial, I’ll explain the difference between the two styles of programming and give real-world examples on how and why you might use each. This tutorial isn’t language-specific and I won’t use any code examples, but by the end of it, I think you’ll have a better understanding of object-oriented programming and how you can apply it in your own code projects.

When creating a PHP application, it is usually necessary to connect to a database to perform certain tasks. In some cases you only want to open a connection when necessary, but limit it to a single connection. This way you don't waste resources on unnecessary database connections. For these situations I use the Singleton Pattern, which is perfect for this.

To calculate the remainder of a subscription time in PHP we need three items: the end date from the future in timestamp format, the current date in timestamp format, and a function to convert the difference between the two from seconds into days, months and maybe even years.

Protect your downloadable content by storing the files outside your webroot. This is an easy solution to online subscription content protetcion.

PHP supports MySQL prepared statements using the Mysqli (MySQL Improved) extension in PHP 5 via the MySQLi_STMT class. They are fairly easy to use once you get used to the differences from writing raw SQL statements. This tutorial will explain how to use prepared statements.

PHP 5 includes a powerful set of DOM manipulation classes that gives you full control over HTML and XML documents. This functionality behaves very similar to JavaScript's DOM manipulation engine. In this tutorial, we'll use the PHP DOMDocument class to load and modify an HTML5 template.

There are many benefits to writing clean code for any project, no matter how small. The importance of clean code becomes most apparent when you need to find an error, especially a syntax error. In the end, cleaner code means less time reading and more time coding!

Sometimes, you might need to convert an integer representing seconds into a format that is easier to read. These functions can be used to turn a number of seconds into a simple format of HH:MM:SS, with leading zeros (ex. 15272 = 04:14:32). This can be used for countdown scripts, which is why I also include both a PHP and a JavaScript version.

Simple yet customizable function that allows you to generate random strings using characters from multiple sets e.g. upper case, lower case, digits and symbols. The random strings can be used in various systems where short, random strings are needed; such as login systems (random password generation) and referral/promotional/discount codes. The coder can specify and change the complexity of string with ease. Few examples presets and output included.

Refactoring is changing of complex and complicated programming codes into simple and confusion-less ones, thereby restructuring the complete set of codes into easily readable formats, without any change in the output or functionality.Refactoring does not include fixing of glitches or including of new functionalities or practices to the existing set of codes.

Any code when written in a clean, easy to understand and formatted way is readily accepted and acclaimed by one and all. It is essential that the codes we write should be able to be understood by all, because the same programmers need not necessarily work on the same set of codes always.

You might have noticed some sites having their URLs written as if they were different subdomains of the same domain. You can do this without creating the actual subdomains, using Apache mod_rewrite. Read this tutorial to learn how!

This tutorial explains how to raise a number to the power of another using PHP using the pow function, for example 3^5.

A tutorial explaining how to find the mathematical roots of a number using PHP, for example square root, cube root, and higher roots.

The code sample demonstrates the use of GD library to apply round corners on an image on-the-fly. It allows you to apply round corners of arbitrary size and color on a GIF, JPEG or PNG image. The source image is read on-demand and sent directly to the browser. This script can potentially eliminate the need of a graphics editing program to apply round corners on tons of images plus revising the images (e.g. when the color scheme or layout of the website changes) is not required.
