PHP在数组内部回显$ config

Alright so I've got a config file that looks like this:

<?php
# EPICMC CMS CONFIG FILE 

return array(
    'sitename' => 'EPICMC',
    'color' => '00aa00',
    'url' => 'stats.epicmc.us',
    'protocol' => 'https://',
);

And here's my webpage.

              $stats = json_decode($statsJSON);
              if(empty($stats)){
              echo $_GET['player'];
              echo '/16';
              } else {

It let's me echo them in my header.php which is where I included the config by using

 <?php $configs = include('config.php'); ?>

And in my header.php it let me echo things like sitename using:

 <?php echo $configs['sitename']?>

, but my webpage isn't working. Keep in mind the header.php is included (which has the config.php included in it). I'm a PHP newbie, and I'm pretty sure I just echoed them wrong or something. I'm trying to get $sitename, $url, and $color to be dynamic.

A working version:

<?php $configs = include('config.php');
if($_GET['player'] === 0) header("Location: http://" + $configs['url']);
 ?>

You need to use curly braces around the array when using it quoted (or concatenate it).

http://sandbox.onlinephpfunctions.com/code/28fb84721d5c91b0c48279163c967489923f150b

So

echo "$configs['sitename']' - ";

Should be

echo "{$configs['sitename']}' - ";

or could be

echo $configs['sitename'] . "' - ";

Documentation (for the curly (complex) usage): http://php.net/manual/en/language.types.string.php#language.types.string.parsing.complex

A separate issue earlier in your code is

$statsJSON = file_get_contents($configs['url']/api.php?task=stats&player='.$_GET['player'].'');

you need to concatenate the arrays value with the query string

$statsJSON = file_get_contents($configs['url'] . '/api.php?task=stats&player='.$_GET['player']);

You should turn on error reporting to get all errors that your script is running into.

How to get useful error messages in PHP?

To enable and display errors add

error_reporting(-1); // to enable all errors ini_set('display_errors', 1); ini_set('display_startup_errors', 1);

don't do this on a production machine though, you don't want users encountering errors.
