如果文件存在，则找不到以.php结尾的文件[复制]

I need to check if a file exist but the system cannot find the file, it may be because the code is ending the $var with .php I dont know. Here is the code

  $thefile=$_POST['files'];
    if (file_exists('/infrastructure/datacenter/'.$thefile.'.php'))
{include('infrastructure/datacenter/'.$thefile.'.php');}

Any idea why the file cannot be found? Because the file really exist

the file name in the test is 2001.php and it does exist but php says it does not exist

There was a missing / in the include second path

You have the if statement checking an absolute path, while your include statement is relative.
