PHP can't fopen remote file

问题

I'm making a script to open remote file (ftp) and edit it with fopen and fwrite.I have problem while connecting to ftp.I made this code

     $handle =        fopen("ftp://".$ftp['username'].":".$ftp['password']."@".$ftp['server']."/cstrike/addons/amxmodx/configs/users.ini", "w") or die("ftp error");
fwrite($handle,$text."\n") or die('err2.');

al variables are set.I tried with ftp://... in web page and it works.allow_url_fopen is On... It just says "ftp error"

回答1:

The ftp:// handler only allows creating new files with fopen("ftp://...", "w");.

If the file already exists you can only write to it if you open it with overwriting set, i.e mode w+.
