The following code adds the properties of books:
<?php class Book { public $isbn; public $title; public $author; public $available; } /* w w w . j av a 2 s . c o m*/ $book = new Book(); $book->title = "2018"; $book->author = "C"; $book->available = true; var_dump($book); $book1 = new Book(); $book1->title = "2018"; $book2 = new Book(); $book2->title = "C++"; var_dump($book1, $book2); ?>
When creating multiple instances of an object and assigning values to their properties, each object will have their own values
