In this tutorial, you will learn about PHP Looping step by step. So without much to do, let’s get started.
What is PHP?
• PHP is an acronym for “PHP: Hypertext Preprocessor”
• PHP is a widely-used, open source scripting language
• PHP scripts are executed on the server
• PHP is free to download and use
PHP is an amazing and popular language! It is strong enough to be on the center of the biggest blogging system on the web (WordPress)! It is deep enough to run large social networks! It is also easy enough to be a beginner’s first server side language!
In the following chapters you will learn how to repeat code by using loops in PHP.
PHP Loops
Often when you write code, you want the same block of code to run over and over again a certain number of times. So, instead of adding numerous almost same code-lines in a script, we can use loops.
Loops are used to execute the equal block of code again and again, as long as a certain condition is true.
In PHP, we have the following loop types:
• while – loops through a block of code as long as the specified condition is true
• do…while – loops through a block of code once, and then repeats the loop so long as the specified condition is true
• for – loops through a block of code a specified number of times
• foreach – loops through a block of code for each element in an array
The following chapters will explain and give examples of every loop type.
