Question

I tring to check if a folder is empty but I keep getting this error

Warning: file_exists() expects parameter 1 to be string, array given

if(!file_exists(glob('/upload/'.$id.'/temp/*'))){
$smeg = 'empty';
}

Answer 1

glob returns an array type.

Change your code like this

foreach(glob('/upload/'.$id.'/temp/*') as $filename)
{
    if(!file_exists($filename))
    {
       $smeg = 'empty';
    }
}
