I have updated the patch file.
Test to reproduce the bug :
1.Create a table with not null field
2.Add trigger filling this field before insert
3.Try from PHP insert null value in the way of "ibase_query($dbh, "insert into hua values
(3,?)",null)", which is the key for the reproduction. And if we insert null value in the
way of "ibase_query($dbh, "insert into hua values (3,null)")", there is no
error.

Description:
------------
As described in https://bugs.php.net/bug.php?id=54426, Wrong NULL
checks was found. However, we find that the bug is not well repaired. And we can still reproduce the
bug.
Removing the "continue" statement in the block of Null check code in ibase_query.c should
be make everything work well:
Modified: php/php-src/trunk/ext/interbase/ibase_query.c

< continue;

> //continue;

Test script:
---------------
The two simple test scripts can be available at https://sourceforge.net/projects/wautorepair/files/test%20cases/
1)create a table like "createtable.php";
2)insert a NULL value like "huahua.php"
then, some errors will occur.
