It has come to my understanding that we have engineering students with no background in HTML.
The extent to which you use it in this course is minimal. The H&L tutorial and the handbook has many exampels, but you may want to Google for HTML crash course.
This one explains text formatting e.g. change colour of text, aligning text etc

Here is help on using forms in PHP
http://www.tizag.com/phpT/examples/formex.php
If you want to use PHP code in a form, you can do it in several ways
Language: PHP
<input type="checkbox" value=" <?php echo "$name"; ?> " name="name" /> // echo the $name which you have extracted from the database back into the form. Just echo the variable with PHP
echo "<input type=\"checkbox\" value=\"$name\" name=\"name\" />"; // echo the whole form element with php. Use \ to escape the double quotes, becasue you cannot use double quote inside double quotes
echo "<input type=';checkbox'; value=';$name'; name=';name'; />"; // echo the whole form element with php. Use single quotes. I suggets you use either the top two ways.
