(PHP 5, PECL oci8 >= 1.1.0)
oci_commit — Commits outstanding statements
Commits all outstanding statements for the active transaction on the Oracle connection .
Returns TRUE on success or FALSE on failure.
Example #1 oci_commit() example
<?php
// Login to Oracle server
$conn = oci_connect('scott', 'tiger');
// Parse SQL
$stmt = oci_parse($conn, "
                          INSERT INTO
                                     employees (name, surname)
                               VALUES
                                     ('Maxim', 'Maletsky')
                         ");
/* Execute statement
   OCI_DEFAULT tells oci_execute()
   not to commit statement immediately */
oci_execute($stmt, OCI_DEFAULT);
/*
....
Parsing and executing other statements here ...
....
*/
// Commit transaction
$committed = oci_commit($conn);
// Test whether commit was successful. If error occurred, return error message
if (!$committed) {
    $error = oci_error($conn);
    echo 'Commit failed. Oracle reports: ' . $error['message'];
}
?>
Note: Transactions are automatically rolled back when you close the connection, or when the script ends, whichever is soonest. You need to explicitly call oci_commit() to commit the transaction, or oci_rollback() to abort it.
