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 "Kai Jim Refsnes";
}
writeMyName();
?>
</body>
</html>
