MySQL: LAST_INSERT_ID() returns 0

Question

CREATE TABLE IF NOT EXISTS `test` (
    `id` INT(10) AUTO_INCREMENT,
    PRIMARY KEY (`id         


        

Answer 1

I had the same issue. mysql_insert_id() or LAST_INSERT_ID() returned 0 when requested inside a PHP function with an INSERT query.

I sorted the issue by requesting the value of mysql_insert_id() from a separate PHP function called right after the function that INSERT query.
