Subject: [PATCH]  r1154@dev030 (orig r57962):  jwang | 2007-08-31 16:45:53
 -0700  Summary: Checking in fix to TFileTransport to remove redundant
 behavior of readEvent -- just return NULL or the next event  Also, checking
 in changes to the php generation code I made awhile ago, but forgot to check
 in

 Reviewed By: aditya, mcslee

 Test Plan: Compiled thrift and falcon, and confirmed that falcon's print binary still worked

 Revert Plan: revertible
