回复讨论(解决方案)

$stmt->bindParam(1, $return_value, PDO::PARAMINT | PDO::PARAM_INPUT_OUTPUT, 8);

$stmt->bindParam(1, $return_value, PDO::PARAMINT | PDO::PARAM_INPUT_OUTPUT, 8);

一样的错误, 

您的存储过程没有声明传入参数,怎么能 CALL para_out(?) 呢?

请教,那应该怎么写,让它返回5 , 谢谢,

唉,没人回答~~~~

人呢,

坐等答案

$stmt = $dbh->prepare("CALL para_out(?)");
改成
$stmt = $dbh->prepare("CALL para_out(@?)");
试试
