PHP rename function can not be used, how to solve

PHP's rename function doesn't work.
Save As Usefile5_for_rename.php

$filepath = "c:/users/administrator/desktop/new Folder/";
$readarray =file ($filepath. " Sub-set synopsis. txt ");
$sign 1 = "First";
$sign 2 = "Set";
$nameArray =array ();
if (! $readarray) {
echo "Failed to read the file with the filename function
";
}
Else
foreach ($readarray as $value) {
if (Strstr ($value, $sign 1) &&strstr ($value, $sign 2))
Use Strpos to pay attention to the byte bits of Chinese characters
Array_push ($nameArray, $value);
else echo "not found";
}
echo sizeof ($nameArray). "
";

To rename a file by order

$i = 1;

foreach ($nameArray as $value) {
$value =trim ($value); It is necessary
echo $value. "
";
$filename = $filepath. " (". $i.") ".". TXT ";
$value = $filepath. $value. ". TXT ";
Rename ($filename, $value);
$i + +;
if ($i >10) break; Total number of files in folder
}

Renaming files by mapping

echo "";
?>

/*
Because the current path is a usefile5_for_rename.php file path, and I want to modify the 10 files in the $filepath directory:

Formerly known as (i). txt (i=1,2,3...,10);

If you cut the file in the current path using:

$filename = "(". $i. ")". ". TXT ";
$value = $value. ". TXT ";
Rename ($filename, $value);
can achieve

So why not under the absolute path?

------Solution--------------------
This seems to be a php5.3 bug, has not been corrected yet?
------Solution--------------------
is not required permission, not set to. It's not clear, is that upstairs?
