Answer 1

You need to use double quotes " for your strings in order for variables to be evaluated. Escape the double quotes in your HTML to have one long string.

Alternatively, you can use concatenation, allowing you to use single quotes around your HTML, and then concatenating the evaluated variables in between, like so:

echo '<td ><div class="iddiv"> <input name="" type="text" value="'.$numq2.'" />   <div>    </td> ';

Answer 2

Just use your echo like this:

echo '<td ><div class="iddiv"> <input name="" type="text" value="' . $row['username'] . '" />   <div>    </td> ';

Answer 3

wrong quote use.

use either

echo '...value="'.$numq2.'" />...';

or

echo " ... value=\"$numq2\" /> ...";

Answer 4

This

echo '<td ><div class="iddiv"> <input name="" type="text" value="$numq2" />   <div>    </td> ';

should become

echo '<td ><div class="iddiv"> <input name="" type="text" value="'.$numq2.'" />   <div>    </td> ';

Notice the '. and .' around your $numq2

Answer 5

You are using single quotes around your string.

Anything wrapped in single quotes gets output as is, and does not get parsed.

Double quotes runs your string through the parser and any variables get replaced with their values.

You need to either break out of the single quotes and concatenate your variable as follows:

echo 'My value ' . $value . ' is the best value';

Or you need to wrap your string in double quotes and wrap your variable in { } as follows:

echo "My value {$value} is the best value";

Answer 6

try

echo <td ><div class="iddiv"> <input name="" type="text" value="<?php echo $numq2;?>" />   <div></td>';
