Can I set a PHP class property from an existing variable?
- by jasondavis
I am trying to figure out how I want to handle settings in my PHP app. I have pretty much decide that I would like to use a Confg class file so it will be autoloaded and flexible in the future. Below is some stuff I was playing with.
I know you cannot set a variable to popluate a Constant so I then try to use a public static property.
Why can I not set public static $ip = $_SERVER['REMOTE_ADDR']; ??
<?php
// config.class.php
class Config
{
const URL = 'http://www.foo.com';
const DB_User = 'dbname';
public static $test = 'test string';
public static $ip = $_SERVER['REMOTE_ADDR'];
}
///////////////////////////////////////////////////////
//index.php
// works
echo Config::URL;
// works
echo Config::$test;
// DOES NOT WORK
echo Config::$ip;
?>
