英文:
Explode doesn't work with a string coming from JS
问题
<script>
// 当按钮被点击时
let tags = ''foo,bar'';
elem.innerHTML += `<x-post tags="${tags}"></x-post>`
</script>
@php
var_dump($tags); // string(9) "foo,bar"
$tags = explode(',',$tags); // 分割字符串
echo "<br>";
var_dump($tags); // array(1) { [0] => string(9) "foo,bar"}
@endphp
英文:
Javascript
<script>
// when button clicked
let tags = 'foo,bar';
elem.innerHTML += `<x-post tags="${tags}"></x-post>`
</script>
post.blade.php
@php
var_dump($tags); // string(9) "foo,bar"
$tags = explode(',',$tags); // exploding
echo "<br>";
var_dump($tags); // array(1) { [0] => string(9) "foo,bar"}
@endphp
How can I fix it? And why this is working correctly when I write tags="foo,bar"?
Expecting: array with foo and bar.
Tryed: JSON.stringify(), array, array with JSON.stringify().
Actually, I'm sending a post with tags via ajax so that they load after clicking on the button, like pagination. It works without tags, but such a problem has arisen with them.
Maybe you know how i can normally send an array to a blade component like in php?

这可以通过创建一个额外的组件来解决。毕竟，问题在于我试图在php中处理字符串。
let html = '';
html += `<x-post title=${post.title}>${post.content}`;
tags.forEach(function(tag){
html += `<x-tag>${tag.name}</x-tag>`;
})
html += `</x-post>`;
elem.innerHTML += html;
英文:
This can be solved by creating an additional component.
After all, the problem is that I tried to process the string in php
let html = '';
html += `<x-post title=${post.title}>${post.content}`;
tags.forEach(function(tag){
html += `<x-tag>${tag.name}</x-tag>`;
})
html += `</x-post>`;
elem.innerHTML += html;

你使用双引号将 tags 作为字符串文字发送，即 <x-post tags="${tags}"></x-post>，因此返回的是 $tags 的总长度为9。
尝试不使用双引号，
<script>
// 在JS中
let tags = 'foo,bar';
elem.innerHTML += `<x-post tags=${tags}></x-post>`
</script>
// post.blade.php
@php
var_dump($tags); // string(7) "foo,bar"
$tags = explode(',',$tags); // 分割
echo "<br>";
var_dump($tags); // array(2) { [0]=> string(3) "foo" [1]=> string(3) "bar" }
@endphp
希望这有所帮助 
英文:
You're sending tags in string literal with double quotes i.e. <x-post tags="${tags}"></x-post> and therefore it's returning the total length of $tags 9.
Try without double quotes,
<script>
//in JS
let tags = 'foo,bar';
elem.innerHTML += `<x-post tags=${tags}></x-post>`
</script>
// post.blade.php
@php
var_dump($tags); // string(7) "foo,bar"
$tags = explode(',',$tags); // exploding
echo "<br>";
var_dump($tags); // array(2) { [0]=> string(3) "foo" [1]=> string(3) "bar" }
@endphp
