finding the position of data in an array? is that the count() function?

I have an array multiple columns... its list the users, score and the game name. users can have multiple games at different scores

user_id     score      Game

1                  1000     tanks
3                 500      tanks
7                 200       submarine
1                  2000    submarine
9                 750       tanks
8                 745       tanks
1                  2000    space

I need to find for a particular user their rank for a particular game.

for example what rank is user 9 in tanks? I know I need ORDER BY score DESC, WHERE 'game' = 'tanks' but the actual counting bit has be baffled.

I'm tempted to use a for while loop but this seems clumsy?

is there a PDO/MySQL solution?

If you want to search a particular data in an array there is this function array_search

this seems to return the specific key associated with the array? i just need the position in an ordered array when WHERE conditions are set....
