Example #1 MysqlndUhConnection::listFields() example

public function listFields ( $res , $table , $pattern ) {
printf ( "%s(%s)\n" , __METHOD__ , var_export ( func_get_args (), true ));
$ret = parent :: listFields ( $res , $table , $pattern );
printf ( "%s returns %s\n" , __METHOD__ , var_export ( $ret , true ));
return $ret ;
}
}
mysqlnd_uh_set_connection_proxy (new proxy ());
$mysql = mysql_connect ( "localhost" , "root" , "" );
mysql_select_db ( "test" , $mysql );
mysql_query ( "DROP TABLE IF EXISTS test_a" , $mysql );
mysql_query ( "CREATE TABLE test_a(id INT, col1 VARCHAR(255))" , $mysql );
$res = mysql_list_fields ( "test" , "test_a" , $mysql );
printf ( "num_rows = %d\n" , mysql_num_rows ( $res ));
while ( $row = mysql_fetch_assoc ( $res ))
var_dump ( $row );
?>
以上例程会输出:
proxy::listFields(array ( 0 => NULL, 1 => 'test_a', 2 => '', )) proxy::listFields returns NULL num_rows = 0
