PHP: Overwriting files

RobertFoster

Hello,

I set up a fairly basic PHP script which allows me to upload and download college work from whereever I am (home or college)

I have a bit of a problem when trying to overwrite a file already in existance. I get the following error message:
[PHP]Warning: copy(<directory>/<filename>): failed to open stream: Permission denied in /****/*******/public_html/college/upload.php on line 14[/PHP]
Said line 14 is:
[PHP]if (copy ($file, "$dir/$file_name")) {[/PHP]
If you want me to put up the full scripts I will.

I googled for a bit, but it was fruitless - results returned were about some premade script.

Anyone got any ideas?

Have a look at

chmod($filename, $permissions);
[PHP]
<?php
function file_write($filename, &$content) {
if (!is_writable($filename)) {
if (!chmod($filename, 0666)) {
echo "Cannot change the mode of file ($filename)";
exit;
};
}
if (!$fp = @fopen($filename, "w")) {
echo "Cannot open file ($filename)";
exit;
}
if (fwrite($fp, $content) === FALSE) {
echo "Cannot write to file ($filename)";
exit;
}
if (!fclose($fp)) {
echo "Cannot close file ($filename)";
exit;
}
}
?>
[/PHP]
