When validating dates in PHP you can either do it the hard way, by spending some time putting together a regular expression, or the easy way, by using a predefined function.

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.

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.

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 explore the DOMDocument class by generating an entire HTML5 page without writing a single bit of raw markup. This may not be practical for most applications, but it should give you a good idea of how the basic DOMDocument methods work.

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.

First of all try to collect the necessary information which are important to display the actual month and highlight the actual day.

The last day of the actual month

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.

With many software frameworks available online nowadays, with many pros and cons on their side, it has become very important to check out complete details of these frameworks before applying them. Amongst the various kinds of software frameworks, the PHP Framework is more popular nowadays.
