Loops are another important factor in PHP and all programming languages. They can be used for a multitude of different things, including but not limited to skipping through arrays, searching for data, etc. The structure of a while loop is similar to the basic structure of if statements, which was explained in a tutorial earlier. The while loop structure is as follows: while a condition is true, do something. Please take a look at the below code. Read More...

If you have a multiple strands of related information that you'd like to have together, arrays are the way to go. They allow you to set multiple peices of information to one variable and output them based on a numerical pointer. What I've just said may sound confusing, however when you see the code below it'll all seem a lot easier.

It's hard to explain what comments are in any other way than saying that comments are comments. Rather than trying to explain, I've coded an example below.

Operators in PHP are a useful way to use mathematics on variables. Whether you want to add, subtract, multiply, divide, or do any other mathematical equation involving a variable or variables, operators are the way to go. The PHP operators are generally the same as mathematical operators which makes them very easy to learn. Below shows examples of how to use basic operators with variables. Read More...
When learning PHP, most people get introduced to the PHP functions with the most basic of all functions -- the echo() function. The echo() function tells PHP to echo things into the browser's viewing area. You can pass either variables or raw text to the echo function. Since we learned about PHP variables in the latter tutorial, I'll start off by demonstrating how you can echo the information stored in variables using the echo() function. See the code below.

Using variables in PHP is done in every single script, and is extremely basic PHP knowledge. If you have experience in any other programming languages, you'll know that all languages use variables. Variables are basically peices of code that hold information. Read More...
When starting out with PHP, the obvious, and most important thing you'll need to know is how to designate the area where the server's PHP parser will start reading your code. As with most web page, PHP is used in conjunction with HTML.
