答
You could do it that way (note that there are other solutions to this problem) :
public function save() {
$properties = get_object_vars($this);
print_r($properties);
// do something with it.
}
答
You can find properties in an object with:
$properties = get_object_vars($book);
答
here is complete code that you should use:
<?php
class Book
{
public function save()
{
$vars = get_object_vars($this);
var_dump($vars);
}
}
$book = new book;
$book->id = '1';
$book->name = 'some';
$book->save();
?>
</div>
