Remove empty rows on table with php - php

Question

I have table:
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" integrity="sha384-GJzZqFGwb1QTTN6wy59ffF1BuGJpLSa9DkKMp0DgiMDm4iYMj70gZWKYbI706tWS" crossorigin="anonymous">
<table class="table-bordered" width="100%">
<tr>
<th>Product</th>
<th>Service</th>
</tr>
<tr>
<td>Product 1</td>
<td>S11</td>
</tr>
<tr>
<td></td>
<td>S13</td>
</tr>
<tr>
<td></td>
<td>S14</td>
</tr>
<tr>
<td>Product 2</td>
<td>S11</td>
</tr>
<tr>
<td></td>
<td>S120</td>
</tr>
</table>
I need: where empty row with product (where product's name is empty) delete this row and move service to up product row and delete current service from up product. Example:
In this table we have product 1. I need remove S11 and paste: S13 and S14 in single row.
I need this table on result:
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" integrity="sha384-GJzZqFGwb1QTTN6wy59ffF1BuGJpLSa9DkKMp0DgiMDm4iYMj70gZWKYbI706tWS" crossorigin="anonymous">
<table class="table-bordered" width="100%">
<tr>
<th>Product</th>
<th>Service</th>
</tr>
<tr>
<td>Product 1</td>
<td>S13, S14</td>
</tr>
<tr>
<td>Product 2</td>
<td>S120</td>
</tr>
</table>
I know how it can do with javascript:
let tr;
$('#test1234 tr').each(function () {
if($(this).find('td:nth-child(1)').text().length){
tr = $(this);
tr.find('td:nth-child(2)').text('')
}else{
let td = $(tr).find('td:nth-child(2)');
let comma = td.text() !== "" ? ", " : '';
td.text(td.text() + comma + $(this).find('td:nth-child(2)').text())
$(this).remove()
}
});
But I need do this with php. How I can do it?
I have this html page on my php variable: $html_body.

Answer 1

generally you can't remove it using php but i will give you suggestion that please use continue statement when your row is blank
for example
$html = "<tbody>";
foreach($data as $row){
if(empty($row['parameter'])){
continue;
}else{
$html .= "<tr> <td></td> </tr>";
}
}
$html .= "</tbody>";
