chmode problem !!

[hisham]

I tried to use the following code to chmode a directory in my linux box and in my internet host:

<?
$dir=&quot;/usr/local/apache/htdocs/my

http://www/myfolder/&quot;;

if( file_exists( $dir ) ){
if( !is_file( $dir ) ){
chmod($dir,0755);
}
}
?>

but I get the message:
Warning: chmod failed: Operation not permitted in /usr/local/apache/htdocs/my

http://www/dir.php

on line 5

I tried $dir=&quot;/usr/local/apache/htdocs/my

http://www/myfolder&quot;;

And I get the same result. Any help?
Thanks in advance.

According to:

http://www.php.net/manual/en/function.chmod.php

chmod operates on files, not directories.

kubla,
Yes, chmod operates on files. But since everything is a file in the UNIX world, it also operates on devices and directories.

hisham,
Is the webserver user the owner of the file? You have to be the owner (maybe group works too, not really sure on this one) to use chmod and it's similar commands. //Daniel

Daniel,
I think so, because I can chmod it using ftp

Doing it via FTP is different to doing it by code, because they tend to have different permissions (don't know why, permissions aren't really my area)

 

[sleipnir214]

The permission difference is because of who is performing the action.

In FTP, any action you take is based on the user as which you logged in.

In WWW, the script is run as the user the web daemon uses to operate. Permissions need to be relative to that user. Want the best answers? Ask the best questions:

i tried with ftp using the following code:

$dir=&quot;my

http://www/myfolder&quot;;

$cmd = &quot;chmod($dir, 0777)&quot;;
if ($login_result) {
@ftp_site ($conn_id, $cmd);
}

i didn't get error message, but the permission still 755

 

[sleipnir214]

That would be because you're just setting $cmd to the value of a string -- namely &quot;chmod($dir, 0777)&quot; Want the best answers? Ask the best questions:

Correction. You're setting it to the value:
&quot;chmod (my

http://www/myfolder,

0777)&quot;

On PHP 4.3.0 running on Linux, the following code works

<?php

$mydir = 'myfoo/mybar';
$foo = @chmod ($mydir, 0777);
print ($foo === TRUE) ? &quot;worked&quot; : &quot;no joy&quot;;

?>

If and only if the user as which Apache runs is the owner of the directory. Want the best answers? Ask the best questions:
