使用PDO使用Out参数调用存储过程

似乎这里有一个错误在起作用，我发现的最佳解决方案是：

http://www.php.net/manual/zh/pdo.prepared-
statements.php#101993

从以上链接的评论中：

$dbh->query("CALL SomeStoredProcedure($someInParameter1,

$someInParameter2, @someOutParameter)”);
$dbh->query(“SELECT @someOutParameter”);

// OR, if you want very much to use PDO.Prepare(),// insert "SELECT @someOutParameter" in your stored procedure and then

use:

$stmt = $dbh->prepare("CALL SomeStoredProcedure(?, ?)");$stmt ->execute(array($someInParameter1, $someInParameter2));
