Hi Steve,
Using MapScript PHP API, WRAP is a integer member.
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,

I've also tried this, but the map isnt rendering.
$labelObj->set("WRAP", "@");
Thank you very much for your help

and linebreak
When labeling with linebreaks, I insert an unique character like '@', so
"[field1]@[field2]" and then on the label block add
WRAP "@"
Try that and see if it works for you.
