[RESOLVED] deleting array values

[sssphp]

I have an array of filenames and need to delete values based on whether the file exists on my server. Here is the array I'm working with:

$files = array(
'file1.htm',
'file2.htm',
'file3.htm',
'file4.htm'
);

So if files 3 & 4 aren't on my server, then the new array should be:

$files = array(
'file1.htm',
'file2.htm'
);

foreach ($files as $key => $file) {
    if (!file_exists ($file)) {
        unset ($files[$key]);
    }
}

Thanks -- that works great.
