These are the available commands:
<? echo query ?>
The result of the query is send to the output stream This command can also be written as NOT FOUND: = query
<? if query ?> <? else ?> <? endif ?>
When the result of query is true, all the text between if and else (or endif when there is no else) is send to the output stream. When the result of query is false, all the text between else and endif is send to the output stream. An empty object, an empty array or a null value is considered as a false value. For numbers a zero is false. An empty String is also false.
<? ifexist query ?> <? else ?> <? endif ?>
