PHP PDO。查询正确时，错误号“00000” [英] PHP PDO. error number '00000' when query is correct

问题描述

我有下面的代码：

$sql3 = "update news set date='$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]);
}

当我运行脚本时，有时会得到错误号'00000'。我的意思是介绍 IF 。它都是随机的。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] => )

我该如何解决这个问题？

PS：

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 一切工作正常。你碰到错误检查代码的原因是 $ sql3 返回0（没有行受到影响），PHP评估为false。尝试显式检查 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)
