Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' for echo statement with variables
<p>I have a php file where it has a table with check box with the value which is equal to the ID from MYSQL table. When I run it I get the error. 
I know there is some problem with " and ' can any one help in solving this?</p>

<pre><code>    while ($row = mysqli_fetch_array($result))
    {
    echo "&lt;tr&gt;";
    ***//I get error in the following line*** 
    echo"&lt;td&gt; &lt;form action="del_prod.php" method="post"&gt;input type="checkbox" name="product_id" value="$row["product_id"]"&gt;&lt;/td&gt;"
    echo "&lt;td&gt;" . $row['product_id'] . "&lt;/td&gt;";
    echo "&lt;td &gt;" . $row['product_name'] . "&lt;/td&gt;";
    echo "&lt;td&gt;" . $row['weight'] . "&lt;/td&gt;";
    echo "&lt;/tr&gt;";
    }
    echo "&lt;/table&gt;";
    ?&gt;
</code></pre>
