PHP 将 HTML 解析为多维 JSON 数组

Question

我正在解析 HTML 并将多维输出数组作为 json。 我正在解析我想要的 html，但我无法创建 JSON 数组。

foreach 循环的示例输出：

PS：每个 json 对象都有不同的字符串值。

0:"废话"

1:“废话”

2:“废话”

3:“废话”

4:" " // 只有空格

5:“废话”

6:“废话”

7:“废话”

8:“废话”

9:" " // 只有空格

...

我想创建这样的 json 数组：

 $output = array();
    $html = str_get_html($ret);

    $lessons["lesson"] =array();
    foreach($html->find('table//tbody//tr') as $element) {

        $temp = strip_tags($element->innertext);

        array_push($lessons['lesson'], $temp); // the objects (I wrote as 'blahblah' every object but I getting different values always)

        if($temp == " ") // if there is only space push array the output and create new array
        {

            array_push($output , $lessons["lesson"]);
            unset($lessons);
            $lessons["lesson"] = array();
        }
    }
echo (json_encode($output ,JSON_UNESCAPED_UNICODE)); // $output show nothing

感谢您的建议。

如果您的问题是将所有内容都放入数组中，那么下面的内容将带您到达那里。我没有很好地遵循代码，但尝试在 cmets 中解释我的想法。

$json = ["blahblah"
,"blahblah"
,"blahblah"
,"blahblah"
," "
,"blahblah"
,"blahblah"
,"blahblah"
,"blahblah"
," "];


$lessons["lesson"] = []; // I think this is the array you are using
$tmp = []; // Something tmp to hold things
foreach($json as $elm){ //Loop what I assume $html->find('table//tbody//tr') is returning
    if($elm != ' '){//Wait for a ' ' and add to tmp
        $tmp[] = $elm;
    } else {
         $lessons["lesson"][] = $tmp; // This array is done so keep it and restart
         $tmp = [];
    }
}
