I see the variable $this
in PHP all the time and I have no idea what it's used for. I've never personally used it.
Can someone tell me how the variable $this
works in PHP?
It's a reference to the current object, it's most commonly used in object oriented code.
Example:
<?php
class Person {
public $name;
function __construct( $name ) {
$this->name = $name;
}
};
$jack = new Person('Jack');
echo $jack->name;
This stores the 'Jack' string as a property of the object created.
