PHP将文件名附加到数组

Question

I am trying to append filenames to an array in PHP. I have code which reads filenames from a directory "songs" on a server. I simply want each of these filenames to be added to an array. How could I do this?

Here is my PHP.

$target = "songs/"; 
$items = array();
if ($handle = opendir($target)) {
    while (false !== ($entry = readdir($handle))) {
        if ($entry != "." && $entry != "..") {
            foreach($song as $entry) {
                $items[] = $entry; 
            }

            //echo $items;
            echo $entry."\n";
        }
    }
    closedir($handle);
}

You're using the same variable in the foreach loop as you're using to hold the filename from readdir() . So when you do $items[] = $entry; you're adding the iteration variable to the array, not the filename. There doesn't seem to be any reason to add the filename to the array inside the loop, and you should avoid reusing variables like that, it just causes confusion.

$items = array();
if ($handle = opendir($target)) {
    while ($entry = readdir($handle)) {
        if ($entry != "." && $entry != "..") {
            $items[] = $entry;
            foreach($song as $s) {
                // do something with $s
            }

            //echo $items;
            echo $entry."\n";
        }
    }
    closedir($handle);
}
