Also can be done using vim.

Code:
for file in $(grep -l "PATTERN" `find . -name "*.php"`); do vim "+%s:PATTERN:REPLACE:g" "+wq" $file; done;

It can also be accomplished easily with :

perl -p -i -e 's/&/&amp/g' infile

would the above command work?
NO!

Never ever use the same file at both sides of a pipe or redirection. It will be corrupted since process in concurrent. It does not finish and then pass the results as DOS did.

But yes, this is the usage of s/a/b/g construct.
