Some more things to check, as you're running on a 64 bit OS.
Which distro are you using?
Firebird is 32 bit distribution software (1.5 AFAIR was not released in
64bit version) or have you recompiled on your host for 64 bit?

Same question for firebird client and php fb driver.

Which connection type are you using? Direct or TCP/IP?

If you are using direct connection from PHP 5.4, try instead TCP/IP
trough localhost:aliasname.

Did you check your application's same query, using instead isql-fb?

At the moment I've no more clues or suggestion...
