php glob（）找不到任何文件

Question

$directory = $_SESSION['base_url'] . "assets/images/*.jpg";
$images = glob($directory);

This code is not working. If I print out $directory, it matches the directory where I have put some .jpg files. $images just remains empty...

As bsdnoobz answered, this was my solution:

$directory = dirname(dirname(dirname(__FILE__))) . "\assets\images\\"; //escape
$images = glob($directory . "*.jpg");

Answer 1

It looks like $_SESSION['base_url'] points to your app's URL (like http://example.com ). You should use filesystem path instead of URL. Try something like this:

$directory = dirname(__FILE__) . '/assets/images/*.jpg';

Answer 2

$directory = $_SESSION['base_url'] . "assets/images/*.jpg";
$images = glob($directory);

There was an additional ' .

Answer 3

您在/和.jpg之间有一个额外的'
