require_once在可读文件php wordpress网站上失败

Question

I have a php script that is really simple, but requires some of the wordpress includes. I have used the code from their website for most of it but it is failing whenever I try to call the require_once parts of the scripts. here is the relevant code:

$fn = dirname(__FILE__) . '/wp-admin/includes/media.php';
if(!file_exists($fn))
{
    echo 'No File';
}
if(!is_readable($fn))
{
    echo 'File is unreadable';
}
require_once $fn;

Interstingly enough, The only echo that I get when the require_once is uncommented is the full path to the document. The file is both existing and readable. However, when I uncomment the require_once code it comes back with a 500 error.

On a slightly related point. What is the easiest way of debugging php. I haven't found anything that is VS easy yet (or even as easy to debug as Django!!)

Answer 1

PHP has various settings in php.ini for how logging works. You can also set them at runtime. It might be logging to a file somewhere rather than displaying the error. Consider trying:

error_reporting(E_ALL)

To debug your application. Don't leave it on when you're done working with it.
