以上是我的整个代码....你只需要看几下几块php就可以了。我想要的是确保该人正在尝试编辑此帖子的是发布它的人。否则，他们需要在其他地方重新路由。

Answer 1

~~嗯...也许正在尝试if ( intval($rows['userid']) == intva($currentusers))~~

好的，您使用的是错误的变量名称。这是由$ currentuser而不是$ currentusers。

if ( $rows['userid'] == $currentuser)
    echo "true";
else
    echo "false";

Answer 2

您的条件语句没有任何问题，因此它必须是存储在$ currentusers和$ rows ['userid']中的内容的问题。您能否提供更多特定于分配给这两个变量的值的代码？

编辑：您的代码中有拼写错误。您要比较“$ currentusers”而不是“$ currentuser”。试试这个：

if ( intval($rows['userid']) ==  intval($currentuser))
{echo "true";}
else
{echo "fasle";}

Answer 3

根据您的变量名称，$currentusers是一组用户，如果是这样，您可以使用in_array($value,$array);检查其中是否存在值

如果没有，你以错误的方式命名你的变量= D，也许这是一个类型问题。使用intval函数

将它们转换为int值

if(inval($rows['userid']) == intval($currentusers))

php if语句和比较值
