Retrieving Last Inserted ROWID In PHP/OCI

Is it possible to retrieve the rowid of the last inserted Oracle row in PHP? I was trying:

$statement = oci_parse($conn, "INSERT INTO myTable (...) VALUES ( ...)");
$results = oci_execute($statement);
while($row = oci_fetch_assoc($statement)) {
    $rowid = $row['ROWID'];
}

With no luck. I’m getting the error define not done before fetch or execute and fetch at the fetch line.

Answer

Declare:

$var = "AAAV1vAAGAAIb4CAAC";

Use:

INSERT INTO myTable (...) VALUES ( ...)
RETURNING RowId INTO :p_val

Bind your variable to a PHP variable:

oci_bind_by_name($statement, ":p_val", $val, 18);
