I want to delete the file that only contain the name of myimage1.jpg.

i have done using glob like hsz answered like this:

$image_name = "myimage1.jpg";
foreach(glob('./uploads/thumbs/thread/'.$image_name) as $rows) {                
    unlink($rows);        
}

but it doesn't work.
Could you help me?

i forget to add * before my $image_name. so it will become like this:
glob('./uploads/thumbs/thread/*'.$image_name)

To filter out all files that contain myimage1 in the name, use glob

foreach (glob("*myimage1*") as $filename) {
    unlink($filename);
}
