Describe the Bug

When I try to install php using asdf I get 2 errors:

~/.asdf/plugins/php/bin/install: line 10: get_download_file_path: command not found

and

~/.asdf/plugins/php/bin/install: line 64: download_source: command not found

The error from line 64 I belive it's because some how the download file wasn't loaded since the functions exists there at line 22.

Expected Behaviour

install a working version of php.
