One thing you can"™t escape in your PHP journey is arrays, at one point or another they"™ll crop up in your simple script, your project or anything in between. Arrays are relatively to simple to use, but can be a bit daunting for people new to programming or just PHP.
More often than not, new developers tend to repeat a lot of code in their websites and web apps instead of recycling them. Functions give you the freedom to alter code all throughout your website or web app in one place, both convenient and it helps avoid errors!
We"™ll look at why functions should be used, where they should be used, how they should be used and some special techniques you should be using.
Recently I needed to create a page in Wordpress that didn't have the sidebar on it. Took me a wile to find the solution, but the one I found works like a charm. Takes a bit of programming knowledge, but not too bad.

What are regular expressions, how to use them and their support in PHP are main streams of this tutorial.
In computer science an array is a data structure consisting of a group of elements that are accessed by indexing. In most programming languages each element has the same data type, in PHP however each element can be a different data type. Each element of an array has a unique identifying index number. Changes made to one element of an array do not affect the other elements.
Future-proof your site by using the PHP include statement - allowing you to change your site design quickly and easily.
Functions are arguably one of the most useful features of PHP. They allow a programmer to encapsulate sections of code within a structure which can then be executed from anywhere else in the program flow. Functions are instantiated by use of the function keyword, followed by the user-defined function name including a list of parameters between the paretheses
Conditional statements are used in PHP (and in any other programming language) when the programmer wishes to place a branch in the code, where a specific result will occur if, and only if, a set of conditions is matched
Loops in PHP are very useful when you need to perform repetitions of the same code over and over again, or when you need to ensure that you iterate through all possible values of an array, for example. They come in a few different flavours, the most common being “for” loops and “while” loops
Variables are probably one of the most commonly used code constructs you’ll come across while programming in PHP
There are times in programming where you need to keep track of many variables at once. Maybe the current time of day, the number of items in a package or the name of a certain product. These variables may all be very similar too though, you might, for example, need to keep track of the names of all employees in a company, or the number of items inside each of a large number of packages. Arrays can be used to keep track of these multiple values from within one variable.
