Description
creates PHP code to echo a variable, with optional modifier. Modifiers are
No Modifier - does htmlspecialchars($variable)
:h - echos without any change - eg. raw
:u - echos urlencode($variable)
by default variables are assumed to have calling scope, and are prefixed with $t->, however if they
are inside a loop (foreach), then the variables created by the loop are added to the scope and the prefix
is not added.
