mcrypt_list_modes -- Get an array of all supported modes
Description
array mcrypt_list_modes ( [string lib_dir] )
mcrypt_list_modes() is used to get an
array of all supported modes in the
lib_dir.
mcrypt_list_modes() takes as optional
parameter a directory which specifies the directory where all
modes are located. If not specifies, the value of the
mcrypt.modes_dir php.ini directive is used.
The above example will produce a list with all supported
algorithms in the default mode directory. If it is not set
with the ini directive mcrypt.modes_dir, the default directory
of mcrypt is used (which is /usr/local/lib/libmcrypt).
