One thought here is that updating variables_order is fine on the server, but I really don't want to force arc users to muck with php.ini.
This seems to be resolved already but just wanted to add a note - I believe Windows users currently need to modify php.ini to enable the curl extension for arcanist to work. This is from our internal documentation for installing PHP for arcanist:
Browse to C:\tools\php[some version number]. Edit php.ini as listed below.
- Note: The following modifications remove the semi-colon at the start of the line. Semi-colons are comments in .ini files and these changes are uncommenting and updating the lines.
- Find the line ;extension=curl and remove the semicolon.
- Locate the line ;date.timezone = and replace it with date.timezone = UTC to prevent PHP from yelling at you.
