Any help is appreciated.

$id = mysql_insert_id();
$query = mysql_query("INSERT INTO BLAH (ID) VALUES ('$id')");
If i do this it, the echoed $id will be 0. I want to be able to echo the actual number that was put into the database. Is there anyway of doing this without going into the database or would i have to?

(PHP 3, PHP 4 )
mysql_insert_id -- Get the ID generated from the previous INSERT operation
int mysql_insert_id ( [resource link_identifier])
mysql_insert_id returns the ID generated for an AUTO_INCREMENT column by the previous INSERT query using the given link_identifier. If link_identifier isn't specified, the last opened link is assumed.
mysql_insert_id returns 0 if the previous query does not generate an AUTO_INCREMENT value. If you need to save the value for later, be sure to call mysql_insert_id() immediately after the query that generates the value.
Note: The value of the MySQL SQL function LAST_INSERT_ID() always contains the most recently generated AUTO_INCREMENT value, and is not reset between queries.
mysql_insert_id() converts the return type of the native MySQL C API function mysql_insert_id() to a type of long (named int in PHP). If your AUTO_INCREMENT column has a column type of BIGINT, the value returned by mysql_insert_id() will be incorrect. Instead, use the internal MySQL SQL function LAST_INSERT_ID() in an SQL query.
