Perhaps if you understood what that oneliner was doing then you would
appreciate it that a similar statement in any language would look, similar.

How do you mean? It's PHP's job to parse.

OK for the SQL statement you need to construct a string that looks something
like:
INSERT INTO course VALUES ('valueoftermcode', ...)
The significant part is that you have single-quotes inside that string. so to
make things easier for yourself you use double-quotes as your string
delimiter:
"INSERT INTO course VALUES ('valueoftermcode', ...)"
Now you could have used single-quotes as your string delimiter but then you
would have had to escape the single-quotes that appear inside your string so
it would look something like this mess:
'INSERT INTO course VALUES (\'valueoftermcode\', ...)'

Yes, don't do oneliners. Rewrite like so:
$sql_termcode = sqlite_escape_string($termcode);
$sql_semester = sqlite_escape_string($semester);
...
$sql = "INSERT INTO course VALUES ('$sql_termcode', '$sql_semester', ...)";
sqlite_query( $handle, $sql) or die("Error bravo in query [$sql]: " .
sqlite_error_string(sqlite_last_error($handle)));
