Drogba had been without a club since leaving Montreal Impact past year but is still determined to carry on playing even though he accepts he is in the closing stages of his career.
He will join the Phoenix team as a player, but will later transition into an executive position with the "Phoenix MLS expansion franchise".
By the league's arcane and inscrutable player acquisition rules, the Chicago Fire had dibs on Drogba, and by all accounts the club really wanted him, both for his star power and because the team was in desperate need of a proven goalscorer.
Phoenix Rising is hoping the momentum behind the team proves enough to solidify its bid to become an MLS franchise. "Soccer is an worldwide language understood by sports fans all over the world, and we want to help inspire fluency among new fans every where we play throughout North America".

The African National Congress, which has a commanding majority in parliament, has said its members would vote against the motion. But Zuma will be at Walter Sisulu Square in Kliptown attending his 75th birthday rally, organised by the ANC.
Drogba's experience and knowledge of the game will certainly be of big help for everyone involved with Phoenix Rising as they look to be a part of America's top soccer league.
Fitting Drogba into the lineup might seem easy, but it might slow an already late-arriving chemistry that is badly needed by a club that did not score a goal in its first 240 minutes of regular season action this year.
Phoenix Rising FC is now three games into its USL season, winning its first match of the 2017 campaign at the third attempt - a 2-1 win over LA Galaxy II.
Drogba has combined with former NY Red Bulls forward Shaun Wright-Philips and Mexican worldwide Omar Bravo to help the southwestern American club gain status both on and off the field.
'His invaluable mentorship will guide our young stars in the locker room and on the field, contributing to the future success of our league and the game for years to come'. If successful, they'll be the only MLS team in the Southwest, giving them a huge opportunity to tap into a potentially very lucrative market.
