See the PHP MapScript docs for $mapObj->processTemplate() in 
http://mapserver.gis.umn.edu/doc36/phpmapscript-class-guide.html
Only tags that correspond to a member of the mapObj will be replaced in
the template by default.  And if you pass the second argument
(generateimages) as TRUE then the [img], [scalebar], etc. will be
automagically generated and replaced as well.

[map] seems to be specific to the CGI mode, that's why it's not handled
by the function.  According to the MapServer templates docs, it is
enabled only if the SAVEMAP CGI parameter is enabled (apparently to save
the state of the map to a temporary file).

Note that since you have the map path in your script you can pass it via
the first argument to the processTemplate() method.  There is an example
of this in the PHP MapScript docs... not sure how that would work in
Perl though.

I hope that helps.
