why should $ManyFunctionsNeedThisVar in __constrcut(9 be global without "global
$ManyFunctionsNeedThisVar" ir $GLOBALS['ManyFunctionsNeedThisVar'];

this are two different vars in different scopes and you really should learn basics:

Thanks master @dharman

when we declare 

$ManyFunctionsNeedThisVar = 777;

this is GLOBAL.

When we declare

	function __construct(){ // --> this is GLOBAL ?
		$GLOBALS['a'] = 888; // --> this is GLOBAL ?
		$ManyFunctionsNeedThisVar = 777; // --> this is GLOBAL ?
		OtherFunction();
		}

This looks correct to me. $ManyFunctionsNeedThisVar is empty in global scope. I think
your confusion comes from the fact that you have another variable with the same name in a local
scope within the constructor. Local scope and global scope are not the same.

Description:
------------
no't possible pass $VAR to GLOBAL context without used ARRAY $GLOBALS, please see the code.

Test script:
---------------
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

function OtherFunction(){
	GLOBAL $ManyFunctionsNeedThisVar;
	print_r($GLOBALS['a']);
	print_r($ManyFunctionsNeedThisVar);
	}

class OtherClass{
	function __construct(){
		$GLOBALS['a'] = 888;
		$ManyFunctionsNeedThisVar = 777;
		OtherFunction();
		}
	}

$OtherObject = new OtherClass();



Expected result:
----------------
String concatenated, correct output:

888777

Actual result:
--------------
888
