That sounds like it might be a bug in PHP API because in:

https://mapserver.org/mapfile/label.html

MAXLENGTH [ integer]
WARP [character]

You might want to open a ticket and put in what you have tested.
I would also try making a trivial mapfile with a feature and label it to 
see that it works without the PHP mapscript
and then reproduce that in a simple PHP script to submit as examples of 
the issue.

Hope this helps,
