PHP Functions
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.
Example
A simple function that writes my name when it is called:
<html>
<body>
<?php
function writeMyName()
{
echo "Alice John";
}
writeMyName();
?>
</body>
</html>
