novice: how to run .sql script from php?

Hi All, I got this .sql script that setup the whole db schema, I can run mysql.exe to run on my pc but when it goes to a hosting company's server I don't have that command! So I tried to include("setup.sql") into a string and send that as one long sql query. BUT I need to get rid of all the comment lines first in the script!! can someone give me a better idea of doing this. (there must be an equivalent php function like mysql_run_script("setup.sql")) thanks -- Tony Yau
