如何在php中调用存储过程

Question

我在mysql workbench中创建了一个存储过程。我试图在PHP中调用它，我得到以下错误：

Warning: mysql_query() expects parameter 1 to be string, resource given in 
C:\xampp\htdocs\Project1\storedProcedure1.php on line 9

$res = mysql_query($connection, "CALL getPlayers1()") or  
  die("Query fail to launch:".mysql_error());

请问任何建议？

顺便说一句，我的存储过程如下：

DELIMITER $$
    CREATE PROCEDURE GetPLayers()
    begin
    select player_id, name, gender, playing_career,dob,place_of_birth
    from players;
    end $$
