Adding "extension=php_interbase.dll" to the end of php.ini causes Apache 2.2 to fail to start ANY services. Without "extension=php_interbase.dll", ibase_connect fails as an undefined function, so Interbase is not enabled as a service by default even though php.ini contains the basic defaults such as "ibase.allow_persistent = 1".

This system is also running PHPEd, with its associated PHP which works fine. When bypassing Apache and confining the pages to PHPEd, everything works.  The "extension=php_interbase.dll" is in the PHPEd php.ini.  The InterBase server is running on this system, and PHPEd has no trouble finding it without any explicit directions.

Either there is another way to enable InterBase on 5.35, or something is wrong. 

Test script:
$DB=ibase_connect('', $DBUser, $DBPass);

Expected result:
ibase_connect should be recognized as a valid function.

Actual result:
ibase_connect is declared an undefined function.

Have you followed the instructions at -- in particular,
ensuring that gds32.dll is in the PATH?

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

The Firebird libraries are required to use interbase extensions. They have to be 
in your PATH. Test it under CLI to see the error (DLLs not found) or enable/read 
apache's error log.
