PHP - 将文件复制到文件夹

i have problem to copy same file name ex : 00000.php to the same folder (00000) note : folder & file (.php) was create by "Hash" code. it's my code :

<?php
header ('Location: admin.php');

// Variables
$ads= $_POST['ads'];
$navbar = $_POST['navbar'];
$slider = $_POST['slidermenu'];
$news = $_POST['news'];
$items = $_POST['items'];
$footer = $_POST['footer'];
$rand = md5($_SERVER['REMOTE_ADDR'] . time());
// File Open
chdir("../pages/");
mkdir($rand);
$filename = fopen($cd . $rand . "." . "php" ,"a"); 
copy($filename,$rand);


// Should Include It's Head (Css / Js)
fwrite($filename,'<?php include($_SERVER["DOCUMENT_ROOT"] . "/include/settings.php"); ?>');
fwrite($filename,"
");


// Start Function For Radio Boxs
if ($ads == "ads-yes") {          
fwrite($filename,'<?php include($_SERVER["DOCUMENT_ROOT"] . "/include/ads.php"); ?>');
fwrite($filename,"
");    
}

if ($navbar== "navbar-yes") {          
fwrite($filename,'<?php include($_SERVER["DOCUMENT_ROOT"] . "/include/navbar.php"); ?>');
fwrite($filename,"
");    
}

if ($slider == "slidermenu-yes") {          
fwrite($filename,'<?php include($_SERVER["DOCUMENT_ROOT"] . "/include/slider.php"); ?>');
fwrite($filename,"
");    
}

if ($news== "news-yes") {          
fwrite($filename,'<?php include($_SERVER["DOCUMENT_ROOT"] . "/include/news.php"); ?>');
fwrite($filename,"

You don't try to copy a file which is currently opened by PHP before writing data to that file, are you?

Its like everything on the computer: You should first WRITE the file before trying to copy it.

ALSO you try to create a file in its folders location.

What are you copying:

/example.php to /example -> copy($filename,$rand);

What are you trying to copy:

/example.php to /example/example.php -> copy($filename,$rand."/".$filename);
