Hello

I've corrected the first bit of code.

_music.php_

<html>
<body>

<?php
function getmusic()
// Open a directory, and read its contents
{
$musicdir = array(); // declare and initialise an array like this
$dir = "Music/";

if (is_dir($dir)){
  if ($dh = opendir($dir)){
    while (($file = readdir($dh)) !== false){
      echo $file . "<br>";
      array_push($musicdir, $file); // array_push alters the array in place
    }
    closedir($dh);
  }
  return $musicdir; // missing $ and typo
}
?>

</body>
</html>

You can't (directly) call PHP functions from inside Javascript, or execute
PHP in the browser.

_HTML file_

<script>

var array musicdir() = getmusic();

 while (($file = readdir($musicdir)) !== false){
      echo $file . "<br>";

</script>

In the PHP code, your function prints out the contents of the directory,
so maybe it doesn't need to return an array as well. But you can't mix PHP
and Javascript.
