The <function>mysqli_insert_id</function> 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.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
Performing an INSERT or UPDATE statement using the LAST_INSERT_ID()
|
|
function will also modify the value returned by the
|
|
<function>mysqli_insert_id</function> function.

&reftitle.returnvalues;

<para>
|
|
The value of the <literal>AUTO_INCREMENT</literal> 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 <literal>AUTO_INCREMENT</literal>
|
|
value.

</para>
|

<note>

If the number is greater than maximal int value, <function>mysqli_insert_id</function>
|

will return a string.
