如何在 PHP 中打印对象数组

Question

In my JavaScript file I create this array:在我的 JavaScript 文件中，我创建了这个数组：

const get_rows = () => {
            return document.getElementById("section-content").querySelectorAll('.element');
}
( get_rows() ).forEach( ( item, index ) => {
            currentOrder[ item.id ] = index;
})

When I pass this array(currentOrder) in PHP by ajax, I try to print it, but it gives me当我通过 ajax 在 PHP 中传递这个数组（currentOrder）时，我尝试打印它，但它给了我

[object Object]

So, how can i print in PHP an array of object?那么，我如何在 PHP 中打印一个对象数组？ thanks谢谢

I am trying to give you answer, but because there is no proper explanation so it is quite difficult to understand the proper issue.我试图给你答案，但因为没有正确的解释，所以很难理解正确的问题。 What I find in your case is, you are not defined currentOrder.我在您的情况下发现的是，您没有定义 currentOrder。 I just implemented a small code with html for you.我刚刚为您实现了一个带有 html 的小代码。

 <html> <body> <div id="section-content"> <div id="id1" class="element">hi</div> <div id="id2" class="element">hi1</div> <div id="id3" class="element">hi2</div> </div> <script> console.log("hi"); const get_rows = () => { return document.getElementById("section-content").querySelectorAll('.element'); } var currentOrder = []; ( get_rows() ).forEach( ( item, index ) => { currentOrder[item.id] = index; }) console.log(currentOrder); // Here you have to send currentOrder to your php code. </script> </body> </html>

Second thing is, why you are getting "index" in your array, Its just index of your element inside section-content.第二件事是，为什么要在数组中获取“索引”，它只是部分内容中元素的索引。 If still you have any problem please try to share more code snippets to help us to answer properly.如果您仍有任何问题，请尝试分享更多代码片段以帮助我们正确回答。
