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.

Hi,
Using MapScript PHP API, I want to create a label object (using
tostring expression) and put 2 columns with a linebreak between them.
The example above is working well on a single line, but I don’t know
how to make the linebreak (carriage return).
$text = "(tostring([vol],'%.2f')+'[vol]')";
$classObj = new classObj($layer);
$classObj->setText($text);
$classObj->addLabel(CreateNewLabel($labelProperties));
I've tried multiple combination of \r\n but none of them work (map
rendering work, but the label completely disappear).
$text = "(tostring([vol],'%.2f') + '\r\n[vol]')";
$text = "(tostring([vol],'%.2f') + '\r\n' + '[vol]')";
If I don’t use the expression, the line break work
$text = "'[vol]\r\n[vol]'";
By the way, the TEXT property is on the classObj, the setText method
doesn’t work on the labelObj.
With best regards,
MapServer 7.4.4 (under ubuntu 16.04)
PHP 5.6.40
