Example #1 MysqlndUhConnection::query() example
<?php
class proxy extends MysqlndUhConnection {
public function query ( $res , $query ) {
printf ( "%s(%s)\n" , __METHOD__ , var_export ( func_get_args (), true ));
$query = "SELECT 'How about query rewriting?'" ;
$ret = parent :: query ( $res , $query );
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" );
$res = $mysqli -> query ( "SELECT 'Welcome mysqlnd_uh!' FROM DUAL" );
var_dump ( $res -> fetch_assoc ());
?>
以上例程会输出:
proxy::query(array ( 0 => NULL, 1 => 'SELECT \'Welcome mysqlnd_uh!\' FROM DUAL', )) proxy::query returns true array(1) { ["How about query rewriting?"]=> string(26) "How about query rewriting?" }
