EXAMPLE:
You need to know the generator´s value after INSERT:

Before INSERT-Statement run

$nextnumber=ibase_gen_id ("GEN_NAME",1);

GEN_NAME: is the generator´s name

1: means add 1 to actual value of generator

$nextnumber: is variable to store generators value after incrementing

In the INSERT-Statement you can use $nextnumber instead of using generator directly like in:
INSERT INTO test (field1, field2) VALUES gen_id(gen_test_id, 1), 'testme');

Question arose on php-dev:

How does ibase_gen_id() handle 64bit values?

Interbase 6/Firebird generators are always 64-bit signed integers
(Firebird's BIGINT type), regardless of the platform the client is
running.
On 64-bit platforms, this will never require conversion as PHP's int
type is 64 bits wide on those platforms. On 32-bit platforms, the
generated value is converted to a string if it exceeds the limits of a
32-bit signed integer.
(This behaviour is consistent with the ibase_fetch_*() functions, that
will use strings to represent numerical values that cannot be represented
accurately using native PHP numerical types.)
