Example #1 MysqlndUhConnection::getLastInsertId() example
<?php
class proxy extends MysqlndUhConnection {
public function getLastInsertId ( $res ) {
printf ( "%s(%s)\n" , __METHOD__ , var_export ( func_get_args (), true ));
$ret = parent :: getLastInsertId ( $res );
printf ( "%s returns %s\n" , __METHOD__ , var_export ( $ret , true ));
return $ret ;
}
}
mysqlnd_uh_set_connection_proxy (new proxy ());
$mysqli = new mysqli ( "localhost" , "root" , "" , "test" );
$mysqli -> query ( "DROP TABLE IF EXISTS test" );
$mysqli -> query ( "CREATE TABLE test(id INT AUTO_INCREMENT PRIMARY KEY, col VARCHAR(255))" );
$mysqli -> query ( "INSERT INTO test(col) VALUES ('a')" );
var_dump ( $mysqli -> insert_id );
?>
以上例程会输出:
proxy::getLastInsertId(array ( 0 => NULL, )) proxy::getLastInsertId returns 1 int(1)
