PHP PDO.查询正确时的错误号“00000" [英] PHP PDO. error number '00000' when query is correct

问题描述

我有以下代码:

$sql3 = "update news set date='$time' where id='2'";
$sql3 = $connect->exec($sql3);
if(!$sql3)
{
    print_r($connect->errorInfo());
    $error = $connect->errorInfo();
    die ("Error: (".$error[0].':'.$error[1].') '.$error[2]);
}

运行脚本时，有时会收到错误编号00000".我的意思是它介绍了 IF.而且都是随机的.输出(有时):

When I run the script, sometimes I get error number '00000'. I mean it goes intro the IF. and it is all random. output (sometimes):

Array ( [0] => 00000 [1] => [2] => )

我应该怎么做才能解决这个问题?
PS:脚本每次都正确执行.

What should I do to fix this problem ?
PS: The script executes correctly every time.

推荐答案

PDO 错误代码 00000 表示一切正常.您遇到错误检查代码的原因是 $sql3 返回 0(没有行受到影响)并且 PHP 将其评估为 false.尝试明确检查 return false;

The PDO error code 00000 means that everything works fine. The reason you're hitting the error-checking code is that $sql3 is returning 0 (no rows were effected) and PHP evaluates that to false. Try explicitly checking for a return false;

if($sql3 === false)
