how do i handle concurrent inserts in mysql table and fetch the correct insert id

I am using adodb for PHP library.

For fetching the id at which the record is inserted I use this function

"$db->Insert_ID()"

I want to know if there are multiple and simultaneous inserts into the database table, will this method return me the correct inserted id for each record inserted ?

The reason I am asking this is because I use this last insert id for further processing of other records and making subsequent entries in the related tables.

Is this approach safe enough or am I missing something.

Please help me formulate a proper working plan for this so that I can use the last insert id for further inserts into the other table safely without having to mess up with the existing data.

Thanks

Yes, it's safe for concurent use. That's because LAST_INSERT_ID() is per-connection, as explained here:

The ID that was generated is maintained in the server on a per-connection basis. This means that the value returned by the function to a given client is the first AUTO_INCREMENT value generated for most recent statement affecting an AUTO_INCREMENT column by that client. This value cannot be affected by other clients, even if they generate AUTO_INCREMENT values of their own. This behavior ensures that each client can retrieve its own ID without concern for the activity of other clients, and without the need for locks or transactions.
