I researched this a little more and found this code snippit at line 1100:
ZEND_FETCH_RESOURCE2(mysql, MYSQL *, mysql_link, id, "MySQL-Link", le_link, le_plink);
/* conversion from int64 to long happing here */
return_value->value.lval = (long) mysql_insert_id(mysql);
return_value->type = IS_LONG;
Is there any way that this could be converted into a string before returning? (Forgive me if
I'm over simplifying this...)

If you have a table with an auto_increment BIGINT field:
CREATE TABLE bigtest (
id bigint(20) NOT NULL auto_increment,
PRIMARY KEY (id)
);
and the last ID you inserted was larger than 32 bits:
i.e. 293949384923
If you insert a new record using:
insert into bigtest values (null);
mysql_insert_id() will return an incorrect number usually negative. It looks like it's storing
that large (64bit) number in a 32bit field of some sort before returning it to the caller.
