I have an image browser that creates thumbnails, but I cannot call 'mkdir' to create a directory in my code to put my thumbnails in. I have tried to call 'chmod' on the parent directory as well as the top level directory, but I'm DENIED.

Does this webhost not allow those functions to be called or something?

My code is as follows:

// make the thumbnail directory
if ( !(chmod('.', 0777)) )
{
    echo 'Could not change the directory\'s permissions.<br>';
}
// temporarily change parent permissions
if ( !chmod('/public_html', 0777) )
{
    echo 'Could not change top-level directory permissions.<br>';
}
else
{
    // change them back
    if ( !chmod('/public_html', 0775) )
	echo 'Could not change top-level directory permissions back.<br>';
}
if ( !(mkdir( './thumbnails/', 0777, true )) )
{
    echo 'Could not create directory: ' . $this->path;
    echo '<br>Thumbnails cannot be created.';
    return false;
}

I think it's not allowed. But you can create it via ftp client, chmod it from there.

Permission can be denied because of ownership problems. If you reset ownership in Cpanel, you may be able to fix this problem.

This is because the php scripts are in the 99 group but all the directories under publichtml are in a group of your user name.

To create a directory you have to temporarily change the publichtml directory permissions to 777, do not leave them like this. After the new directory is created change your publichtml back to 775. Once you have created the directory your php scripts can chown and chmod it as much as you like.

Any file's you create through cpanel will be of limits for php to chmod and chown but any files or directories php creates can be modified with chmod and chown from php scripts.

It’s all to do with the permissions and the groups.

Note: some people will say just leave the publichtml as 777 but this means anyone on the server can create a script to delete all your files or run malicious code from your site.

PHP runs as a1234567 (or whatever). Uploads and misc. are assigned to the 99 group. Resetting ownerships in cPanel can solve your prob.0
