If I apply the patch then I get a compile failure with ....

In file included from /opt/php-7.0.1/Zend/zend_API.h:28:0,
                 from /opt/php-7.0.1/main/php.h:39,
                 from /opt/php-7.0.1/ext/interbase/interbase.c:27:
/opt/php-7.0.1/Zend/zend_list.h:66:16: note: expected ‘struct zval *’ but argument is of type ‘struct zend_resource *’
 ZEND_API void *zend_fetch_resource2_ex(zval *res, const char *resource_type_name, int resource_type, int resource_type2);

http://php7.lsces.org.uk/ is now running with 7.0.1 quite happily but it took a while to sort out compiling the update. I can now check out the test script ...

Try again from phone ...
Extension is working fine for me in PHP7 ... looks like it's simply returning the blob ID rather than the text, so suspect the default setting changed? There are warnings compiling, but it passes all of the test suite and the firebird test suite so don't understand why there is a problem here.

sorry, it turns out this extension is broken, far away from working..

it's no need to test the patch I paste... thanks :<

Hmm, seems this is broken, I doubt it even work at the first step...

anyway, I made a patch, but I don't have env to test it, could you please check whether it works?
