PHP Functions:
· PHP Built-in Functions
· User Define Function
Create a PHP Function: A function will be executed by a call to the function.
Example: A simple function that writes my name when it is called:
<?php
function writeName(){
function writeName(){
echo "Kai Jim Refsnes";
}
echo
"My name is ";
writeName();
?>
PHP Forms and User Input: The PHP $_GET and $_POST variables are used to retrieve information from forms, like user input.
PHP Include Files: Assume that you have a standard header file, called "header.php". To include the header file in a page, use include/require:
<?php
include 'header.php'; ?>
<h1>Welcome
to my home page!</h1>
<p>Some
text.</p>
