Enabling phar on Dreamhost shared hosting?
Figured it out. If you add a directory at ~/.php/5.3/ and then put a file called phprc in it with the following line in it
extension=phar.so
then the phar extension gets loaded.
I found you have to put some more lines in the phprc file for it to work in FastCGI mode
extension=phar.so
detect_unicode = Off
phar.readonly = Off
phar.require_hash = Off
suhosin.executor.include.whitelist = phar
