Modified files: (Branch: PHP_5_3)
/php-src/ext/interbase ibase_query.c
Log:
[DOC] PHP5: Prototype for ibase_query should be:
ibase_query([resource link_identifier, [ resource link_identifier, ]]
string query [, mixed bind_arg [, mixed bind_arg [, ...]]]

- Fixed bug #30690: (Resource handle from ibase_execute becomes invalid after return)
- Fixed bug #30907: (ibase_query() crashes (in fact the same bug as #32143)
- Fixed bug #32143: (ibase_query() causing IBserver 7 crash with NULL param as link-id)
- Fixed bug #39056: (Interbase NUMERIC data type error)
- Fixed bug #39397: (invalid statement handle in Unknown on line 0)
- Fixed bug #39700: (NUMERIC error when result precision are 7,8 or 12-14)
- Fixed bug #42284: (duplicate of #39700)
