php-在foreach循环中调用存储过程-仅首先执行

我在数据库中创建了一个存储过程,希望从PHP连续调用多次.
假设这是我的程序：

CREATE PROCEDURE PROC_1(
  IN param1 VARCHAR(255),
  IN param2 VARCHAR(255))
BEGIN
  DECLARE ok INT;
  DECLARE success, failure VARCHAR(255);

  /* several SELECT, IF ... THEN, INSERT and UPDATE operations which then SET ok var to 0 or 1 */
  IF ok = 1 THEN
    SET success = 'Everything went well';
    SELECT success;
    LEAVE;
  ELSE
    SET failure = 'Problem description';
    SELECT failure;
    LEAVE;    
  END IF;
END

我这样做(短版)：

$calls = array(
    "CALL PROC_1('param1', 'param2')",
    "CALL PROC_1('param3', 'param4')",
    "CALL PROC_1('param5', 'param6')",
);

// assuming I'm already connected to DB with $link
foreach ($calls as $i => $call)
{
    echo $i . ': ';
    $result = MysqL_query($call);
    $ok = ($result === FALSE) ? FALSE : TRUE;
    var_dump($ok);

    if ($result !== FALSE)
        MysqL_free_result($result);
}

第一次迭代按预期工作,但是返回FALSE之后的任何事情.
这是为什么？

尝试MysqLi以防万一,但输出完全相同：

0: bool(true)
1: bool(false)
2: bool(false)

有趣的是,我检查了MysqL日志(设置为记录所有查询的日志记录),并且只有第一个查询到达了服务器.下一个查询永远不会到达服务器.

PS.我正在运行PHP 5.3.2和Apache 2.2.17.

UPDATE

根据Shakti Singh的建议,在查询数据库之前,我已经检查了$link状态.我注意到自第二次迭代以来存在错误,因此这是带有错误的输出：

ERROR: (0) 
0: bool(true)
ERROR: (0) 

ERROR: (0) 
1: bool(false)
ERROR: (2014) Commands out of sync; you can't run this command Now

ERROR: (2014) Commands out of sync; you can't run this command Now
2: bool(false)
ERROR: (2014) Commands out of sync; you can't run this command Now

另外,这会出现在MysqL 错误日志中：

101126 15:46:28 [Warning] Aborted connection 129 to db: 'db1' user: 'root' host: 'localhost' (Got an error reading communication packets)

解决方法:

在PHP中,当我们在循环中调用存储过程时,它只需执行一次即可.当存储过程返回任何结果集时,就会发生这种情况.
我遇到了同样的问题.我有一个用于更新表记录的存储过程.

并且本应执行1000行,但仅执行一条记录.

当您的SP返回任何数据集时,它不支持.只需消除OUT var或任何select语句(仅用于任何结果引用),它就可以正常工作.
