Old Summary: problem with fopen over ftp and a related fgets
Status: Analyzed
Bug Type: *Directory/Filesystem functions
Operating System: linux
PHP Version: 4.0.5
New Comment:
The following patch will issue a warning for trying to open a ftp file in anything
other than read/write, - as no other methods are supported by fopen(ftp)
as far as producing errors on 'writing to an ftp file opened read only' - this is more
complex as there is no indicators on the socket to tell wheter it was opened read or
write,
(internally the socket is opened rw as the actual connection is a 2 way communication)

<?php
$file = "user:[EMAIL PROTECTED]/path/file.txt";
if (!($fp = fopen($file, "r+"))) {
echo "error: can't open file<br>";
exit;
}
fputs($fp, "test number one...");
fputs($fp, "test number two...");
fputs($fp, "etc...");
fclose($fp);
?>
-------------------------------
The problem is, that nothing is written in the file even though fopen,fputs and
fclose do not return an error.
If you use fopen($file, "a+") the strings are written to file. But now
the problem is, that fopen tries to create that file even if it already exists.
Ciao,
