Redirection

Hello,

I have Wordpress hosted by free.fr and the first
time I ran redirection 1.7.26 , I got the following warning :

Warning: Invalid argument supplied for foreach() in
on line 87

Obviously "free.fr" displays warning !
After some digging, it seems that if we have

if( is_array($file)) 
{

    foreach ($files AS $file)
    {

        if (is_dir ($file))

            @include_once (dirname ($file).'/'.basename ($file).'.php');

        else

            @include_once ($file);

    }

}

instead of

foreach ($files AS $file)
{

    if (is_dir ($file))

    @include_once (dirname ($file).'/'.basename ($file).'.php');

    else

    @include_once ($file);

}

in the file models/redirection/redirector.php, the warning goes
away.

I'm not very familiar with php but the page [1] mentions that [1] http://fr.php.net/glob

The example on this page will generate a warning if the glob 

function does not find any filenames that match the pattern.

The glob function result will only be an array if it finds some files and the 

foreach statement requires its argument to be an array.

By checking for the possibility that the result of the glob function may not 

be an array you can eliminate the warning.

Here's a better example:
