Need a quick way to run through all php files in a directory (recursively) and see which ones have syntax errors? Here you are my friend:
find . -name "*.php" -type f -print | xargs -I file php -l file | grep -v "No syntax errors detected"
Another way to do this (which if you’re as familiar with find as I am — ie: not very) you could do this as well:
find . -name "*.php" -type f -exec php -l {} \; | grep -v "No syntax errors detected"
