How can I declare a global variable in php

Question

I have code something like this:

<?
    $a="localhost";
    function body(){
        global $a;
        echo $a;
    }

    function head(){
        global $a;
        echo $a;
    }

    function footer(){
        global $a;
        echo $a;
    }
?>

is there any way to define the global variable in one place and make the variable $a accessible in all the functions at once? without making use of global $a; more?

Hello @kartik,

The $GLOBALS array can be used instead:

$GLOBALS['a'] = 'localhost';

function body(){

    echo $GLOBALS['a'];
}

Hope it helps!!
Thank you!!
