PHP use variable from global space inside class -

hi i'm writing code in php. need use variable global scope inside class doesn't work. don't know if need use namespace or not , how ? thank sample :

<?php  $plantask_global_script = array("one", "two"); $plantask_global_config = array("three", "four"); $myvar = array_merge($plantask_global_script, $plantask_global_config);  class env implements arrayaccess {     static private $container = $myvar;      public function offsetset($offset, $value)     {         if (is_null($offset)) {             self::$container[] = $value;         } else {             self::$container[$offset] = $value;         }     }      public function offsetexists($offset)     {         return isset(self::$container[$offset]);     }      public function offsetunset($offset)     {         unset(self::$container[$offset]);     }      public function offsetget($offset)     {         return isset(self::$container[$offset]) ? self::$container[$offset] : null;     } } 

try calling $myvar superglobal:

private static $container = $globals['myvar']; 

although, ron dadon pointed out, bad practice in oop.

edit:

i jumped gun here. above solution does not work, @ least not me. so, better way achieve following:

$myvar = array_merge($plantask_global_script, $plantask_global_config);  class env implements arrayaccess {     private static $container = null;      public static function init($var)     {         self::$container = $var;     }      ... }  env::init($myvar);
