i cant understand it either
but without running your script, does the folder EVER really have 777
you can test this by Refresh your FTP client, or make a new FTP connection to check
you can make a simple test,
by creating a new folder with 777 and in that folder
run the following example
from the official php.net fwrite() manual: http://php.net/fwrite
Example 1. A simple fwrite() example
<?php
$filename = 'test.txt';
$somecontent = "Add this to the file\n";
// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {
// In our example we're opening $filename in append mode.
// The file pointer is at the bottom of the file hence
// that's where $somecontent will go when we fwrite() it.
if (!$handle = fopen($filename, 'a')) {
echo "Cannot open file ($filename)";
exit;
}
// Write $somecontent to our opened file.
if (fwrite($handle, $somecontent) === FALSE) {
echo "Cannot write to file ($filename)";
exit;
}
echo "Success, wrote ($somecontent) to file ($filename)";
fclose($handle);
} else {
echo "The file $filename is not writable";
}
?>
