I am new to using PHP and i am trying to create a script that will create a folder and place a html document in the folder. So far i have done this with the following code

mkdir ("{$rootpath}/{$username}", 0755);
$filename="{$rootpath}/{$username}/index.html";
$file=fopen($filename,"w", 0777);
fwrite($file, "Hello\n");
fclose($file);

But the problem i am having is that once the file index.html is created i am unable to delete it from the sever. I have tried deleting it using WS FTP but it just wont delete. Can anyone tell me how to fix this?

Try this and see if it works:

 
mkdir ("{$rootpath}/{$username}", 0755);
$filename="{$rootpath}/{$username}/index.html";
$file=fopen($filename,"w", 0777);
fwrite($file, "Hello\n");
fclose($file);

unlink($file);

I am not wanting to delete the file using PHP i am just wanting to delete the file at a later date using FTP. But every file i have created using the script at the top will not delete using FTP it just comes up with an error saying "550 Could not delete index.html: Permission denied". This only happens with files created with the php code.

Try chmod($filename, 0777) after creating the file. By default permissions are 644 and the owner is the user which runs the server, usually it is apache, www or nobody. No wonder that you cannot delete the file via FTP.

Also it seems like you should set 777 to the folder also.

try unlink(filename); , If php created it php should be able to delete it.
