This should do what you need:

npp=38 res=$(echo `wc -l`) pretty () { rev <<<$1|perl -pe 's/(\d{3})(?=.)/$1,/g'|rev; } total=$(pretty $(cut <<<$res -d\ -f1)) php -r "echo ceil($TM_LINE_NUMBER/$npp).'/'.ceil($total/$npp);"

I get the following error:

Warning: Wrong parameter count for ceil() in Command line code on line 1 58/
