intinsert_id
The mysqli_insert_id function returns the ID generated
by a query on a table with a column having the AUTO_INCREMENT attribute. If
the last query wasn't an INSERT or UPDATE statement or if the modified table
does not have a column with the AUTO_INCREMENT attribute, this function will
return zero.
Performing an INSERT or UPDATE statement using the LAST_INSERT_ID()
function will also modify the value returned by the
mysqli_insert_id function.
&reftitle.parameters;
&mysqli.link.description;
&reftitle.returnvalues;
The value of the AUTO_INCREMENT field that was updated
by the previous query. Returns zero if there was no previous query on the
connection or if the query did not update an AUTO_INCREMENT
value.
If the number is greater than maximal int value, mysqli_insert_id
will return a string.
