PHP "copy" not working on my Server

[largo]

Hi, I have a flash movie that sends data to PHP and it writes data to an XML file, when the XML file reaches a certain size then PHP makes a copy of the XML and saves it with a new name. PHP then clears the XML and the whole process begins again.

I´ve tried this on my Wamp test Server and it works perfectly there, but now when I'm trying this on a real server the copy function dosn't work, it just cleans the old XML file when the XML file gets too big. It does not save the old data to a new file ....

Could this have something to do with the users permission on the server???

Can someone help me?:confused:

<?php
$filename = "xmldata/egTest1Data.xml";
$raw_xml = file_get_contents("php://input");
$clean_xml = '<?xml version="1.0"?><Tracks></Tracks>';


print $raw_xml;


//Check File Size. The size returned is in BYTES:-------------
$size = filesize($filename);

//If XML file is larger than 100KB's then make a copy.
if($size > 102400){

//Write normally the last entry:---------------------------
$fp = fopen($filename, "w");
fwrite($fp, $raw_xml);
fclose($fp);

//Copy file with new name containing the day it was copied
$today = date("YmdHi");
$newFile = "xmldata/egTest1Data".$today.".xml";
copy($filename, $newFile);

//Overwrite file to clean XML------------------------------
$fp = fopen($filename, "w");
fwrite($fp, $clean_xml);
fclose($fp);


} else {
//Write normally:------------------------------------------
$fp = fopen($filename, "w");
fwrite($fp, $raw_xml);
fclose($fp);
}
?>

Im thinking that the server may be configured differently and you have some undefined variables maybe due to register_globals etc

Check by trying to see these variables exist first, but id recommend another forum for this as its a pure php question, here you have mostly flashers.

Are you certain the account the php process is running as has write access to the folder you want to copy the file to? AFAIK, to edit a file you need write access on the file, but to create a file you need write access on the folder.

Yes, thanks jsebrech :), the problem was with the folder's permission.
