fwrite() problems

[mercuryfenix]

trying to update an xml file from PHP....any help would be appreciated!

it is supposed to open the outdated rss.xml and update it with the latest 6 entries from the table....

must be something wrong with the opening of the file...getting the error:

^{Warning: fopen(rss.xml) [function.fopen]: failed to open stream: Permission denied in /home/mysiteinfo/public_html/mysiteinfo/rss/update_rss.php on line 31}

^{can't open file}

 

<?
///////// Connect to the DB ///////////////////////////////////////////
require_once('../mysql_connect.php');
///////// Getting the data from Mysql table for first list box ////////
$quer2=mysql_query("SELECT * FROM rss ORDER BY rss_id DESC LIMIT 0,6"); 
///////// End of query for first list box /////////////////////////////

$body="<?xml version=\"1.0\" encoding=\"iso-8859-1\"?> 
<rss version=\"2.0\"> 
<channel> 
<title>My Site Name</title> 
<link>http://www.mysite.com</link> 
<description>my site description</description> 
<copyright>(c) 2007, mysite.com. All rights reserved.</copyright> 
";
while($nt = mysql_fetch_array($quer2)) { 
$body .="
<item>
<title>$nt[title]</title>
<link>$nt[link]</link> 
<description>$nt[description]</description>				
<pubDate>$nt[pubdate]</pubDate>
</item>";
}

$body .="
</channel>
</rss>";
echo $body;
$path="rss.xml";
$file_name=fopen($path,"w") or die("can't open file");
fwrite($file_name,$body);
fclose($file_name);
?>

There's probably nothing wrong with your code,

 

failed to open stream: Permission denied

Change the permissions on the file.

I use a shared hosting service online to host the site that this is on....is there a security vulnerability that could cause them to disallow fwrite() on my server? I have checked the permissions and they appear to be right to me.

hmm ok so I scanned through the permissions links posted above...how do I implement a permissions change?

from what I gather I need to do something with

 

$ chmod [references][operator][modes] file1 ...

 

and to give a user named mercuryfenix read and write permissions...

$ chmod u+rw rss

 

what do I do with this?  ??? sorry if this is a nub question!

[mercuryfenix]

ok so i got this far...still getting an error

_{Parse error: syntax error, unexpected T_STRING}

 

with this code...this is just the bottom part of the code from above but modified slightly....i dont understand chmod fully;

$body .="
</channel>
</rss>";
echo $body;
$path="rss.xml";
chmod u+rw rss;
$file_name=fopen($path,"w") or die("can't open file");
fwrite($file_name,$body);
fclose($file_name);
chmod u-rw rss;
?>
