PDO::lastInsertId
(PHP 5 >= 5.1.0, PECL pdo:0.1-1.0.3)
PDO::lastInsertId —
Returns the ID of the last inserted row or sequence value
Description
string PDO::lastInsertId
([ string $name
] )
Note:
This method may not return a meaningful or consistent result across
different PDO drivers, because the underlying database may not even
support the notion of auto-increment fields or sequences.
Parameters
-
name
-
Name of the sequence object from which the ID should be returned.
Return Values
If a sequence name was not specified for the name
parameter, PDO::lastInsertId() returns a
string representing the row ID of the last row that was inserted into
the database.
If a sequence name was specified for the name
parameter, PDO::lastInsertId() returns a
string representing the last value retrieved from the specified sequence
object.
If the PDO driver does not support this capability,
PDO::lastInsertId() triggers an
IM001 SQLSTATE.
