PHP Parsing HTML to multidimensional JSON Array - php

Question

I am working on parsing HTML and get multidimensional output array as json.
I am parsing html like I want but I couldn't create JSON array.
The example output of foreach loop:
PS: every json object has different string value.
0:"blahblah"
1:"blahblah"
2:"blahblah"
3:"blahblah"
4:" " // only space
5:"blahblah"
6:"blahblah"
7:"blahblah"
8:"blahblah"
9:" " // only space
...
I want create json array like this:
$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
Thanks in advice.

If your issue is getting all the blah into the array then the below will get you there. I am not following the code too well but attempt to explain my thoughts in comments.
$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 = [];
}
}
