Warning:in_array() [function.in-array]:Wrong datatype for second argument in D:\wa...on line 12
$filelist=array("muban","login","check");
function filename()
{
$dir=basename($_SERVER['REQUEST_URI'],".php");
if(in_array("$dir",$filelist,TRUE)) //第12行
return $dir;
}

不能把in_array这个函数放到function里面
$filelist=array("muban","login","check");

$dir=basename($_SERVER['REQUEST_URI'],".php");
if(in_array($dir,$filelist, TRUE))
echo $dir;
这样修改即可
再问：为什么？我就是需要把它放在函数里面啊，还有那时个什么原理呢？虽然已经有了别的解决方案了，但想知道问题的本质是什么
再答： php是弱语言
