Try something like:
 
    cat *.php | wc -l

for a single dir, or if in multiple subdirs 

    cat $(find . -iname '*.php') | wc -l

For a count of non-blank lines interpose grep

    cat $(find . -iname '*.php') |grep -vE '^$' | wc -l

(The possibilities are endless. Read the man pages for cat, wc, grep, wc ;-)
