My Answer:
"food"];`_

`echo "";`
`echo "".$food."";`
`echo "";`
`echo "";`
`}`

In this code snippet, you are fetching data from a MySQL database using PHP and printing it in a table row. You want to enter a table row cell from JavaScript.

In the code snippet provided, you are using PHP to print the table rows and cells. If you want to include JavaScript code within the table cell, you can use the `";
echo "";
echo "";
}


In this example, the JavaScript code within the table cell will dynamically generate the content based on the value of the `$food` variable fetched from the database.
