The real power of PHP comes from its functions.
In PHP - there are more than 700 built-in functions available.
*PHP Functions*
In this tutorial we will show you how to create your own functions.
For a reference and examples of the built-in functions, please visit our PHP Reference.
*Create a PHP Function*
A function is a block of code that can be executed whenever we need it.
Creating PHP functions:
* All functions start with the word "function()"
* Name the function - It should be possible to understand what the function does by its name. The name can start with a letter or underscore (not a number)
* Add a "{" - The function code starts after the opening curly brace
* Insert the function code
* Add a "}" - The function is finished by a closing curly brace
