Replace tabs by spaces

I learned something new today:

find . -name '*.php' ! -type d -exec bash -c 'expand -t 4 "$0" > /tmp/e && mv /tmp/e "$0"' {} \;

Of great help to those who want their code to become PSR2 compliant. Works best in Linux but also under Git Bash if you chose to replace DOS utilities with the Unix utilities provided by Git.
