php Scandir（）错误是因为我还是wampserver？

Question

When I use this code (below) it gives me 3 errors. Is it me or Wampserver? What should I do?

<?php
$dir = "/gallery/";
$o = scandir($dir);

print_r($o);
?>

Error 1:

Warning: scandir(/gallery/,/gallery/) [<a href='function.scandir'>function.scandir</a>]: The system cannot find the file specified. (code: 2) in C:\wamp\wwwandom1\index.php on line 3

Error 2:

Warning: scandir(/gallery/) [<a href='function.scandir'>function.scandir</a>]: failed to open dir: No such file or directory in C:\wamp\wwwandom1\index.php on line 3

Error 3:

Warning: scandir() [<a href='function.scandir'>function.scandir</a>]: (errno 2): No such file or directory in C:\wamp\wwwandom1\index.php on line 3

Answer 1

You are searching for the /gallery/ directory. The first / means it'll start searching from the root. Removing that will make it relative. So change

$dir = "/gallery/";

to

$dir = "gallery";
