Quick Reference
The PHP interface keyword is used to create interfaces, which is a structure which defines a list of methods that must exist in a class.
<?php
interface my_interface {
public function activate();
public function deactivate();
public function is_active();
}
class my_class implements my_interface {
private $is_on = false;
public function activate() {
$this->is_on = true;
}
public function deactivate() {
$this->is_on = false;
}
public function is_active() {
return $this->is_on;
}
}
$my_interface = new my_class();
$my_interface->activate();
if($my_interface->is_active()) {
echo 'my_interface is on';
}
else {
echo 'my_interface is off';
}
echo '<br>';
$my_interface->deactivate();
if($my_interface->is_active()) {
echo 'my_interface is on';
}
else {
echo 'my_interface is off';
}
?>
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.

PHP NOTES:
- When using PHP, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
