Why php global declared varible cant be used inside the function?

Question

As the question mention it seems kinda wierd. In most programming language I learn so far, global variable can be used from anywhere. So why doesn't php support this?

Answer 1

For this the $GLOBALS[] is used.
For usage please read in the PHP manual:
http://php.net/manual/en/reserved.variables.globals.php

Answer 2

$GLOBALS['VariableName'] used to access global variables from anywhere .

Example :

$name = 'Zardi' ;

function msg()
{
echo "Name : ".$GLOBALS['name'];
}

msg(); // Name : Zardi

Answer 3
