I'm trying to assign a value from json file to a some kind of global / static variable and then use that global / static variable later down the file.
static $API_KEY = get_api_key(); // gives: Constant expression contains invalid operations
define('API_KEY', get_api_key()); // gives: PHP Notice: Undefined variable: API_KEY in /content.php on line 422
function get_api_key() {
$file_content = file_get_contents("./msx/start.json");
$json = json_decode($file_content);
return $json->tmdb_api_key;
}
I've had my fingers burned by global variables several times over the years, so now I do things a different way.
Create a class for all your code, along with arun() method, and then you can use a class property for your 'global'.
Something like this:
class myClass {
private $apiKey;
public function __construct() {
$this->apiKey = $this->getApiKey();
}
private function getApiKey() {
$file_content = file_get_contents("./msx/start.json");
$json = json_decode($file_content);
return $json->tmdb_api_key;
}
public function run() {
// do stuff using $this->apiKey
}
}
And then invoke it like this:
<?php
$p = new myClass();
$p->run();
