Why not try using an OR for this

为什么不尝试使用OR

if ( (file_exists($target)) || (file_exists($target2)) ) {
    echo "One of the files already exists with the same name.";
    $uploadOk = 0;
}

Try and see if it works. It simply compares if it exists either in 1st target or in the 2nd. Once in exists in any then....

试试看它是否有效。它只是比较它是存在于第一目标还是存在于第二目标中。一旦存在于任何当时....
