解析HTML到多维JSON数组

Question

我正在解析HTML并获取多维输出数组作为json。 我解析HTML像我想但我不能创建JSON数组。

示例输出foreach循环的：

PS：每JSON对象具有不同的字符串值。

0： “blahblah”

1： “blahblah”

2： “blahblah”

3： “blahblah”

4：”“//仅空间

5：“blahblah”

6：“blahblah”

7： “blahblah”

8： “blahblah”

9：”“//只有空间

...

我想创建JSON数组是这样的：

$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 

谢谢你的建议。

如果你的问题是得到所有的数组，然后下面会让你在那里。我没有很好地遵守代码，但试图在评论中解释我的想法。

$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 = []; 
    } 
}
