PHP has doubts about assigning values ​​to class attributes

Test code:

$a = new controller;
$a->test();

classcontroller{public$menuList = time();
    publicfunctiontest(){echo$this->menuList;
    }
}
?>

This will report an error, why

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above introduces PHP’s doubts about class attribute assignment, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
