I would do this:
if (!$AgeChild) $AgeChild = 'NA';
More compact, easier to read (to me, anyway). This presumes that a
value of '' (empty string, interpreted by PHP as false) is NOT a
valid value here.
As far as your sniplet goes, it is possible that there may be some
PHP type-casting issues here, depending on: whether $AgeChild is
numeric or string; the fact that the STRING "false" isn't equivalent
to the CONSTANT false, the use of == vs. ===.
Time to check out the docs - specifically the types and variables
sections (also the functions->variables section)...
