PHP push new key and value in existing object array
提问by Dinizworld
In my study how objects and arrays work with PHP I have a new problem. Searching in existing questions didn't give myself the right "push".
在我研究对象和数组如何与 PHP 一起工作时,我遇到了一个新问题。在现有问题中搜索并没有给我自己正确的“推动”。
I have this for example:
我有这个例如:
$html_doc = (object) array
(
"css" => array(),
"js" => array()
);
array_push($html_doc , "title" => "testtitle");
Why is this not working? Do i need to specify first the key title? Or is there another "1 line" solution?
为什么这不起作用?我需要先指定密钥标题吗?还是有另一种“1 行”解决方案?

array_push() doesn't allow you to specify keys, only values: use
array_push() 不允许您指定键,只能指定值:使用
$html_doc["title"] = "testtitle";
.... except you're not working with an array anyway, because you're casting that array to an object, so use
.... 除非您无论如何都没有使用数组,因为您将该数组转换为对象,因此请使用
$html_doc->title = "testtitle";
回答by Jaaz Cole
You can simply use $html_doc["title"] = "testtitle";
你可以简单地使用 $html_doc["title"] = "testtitle";
