Using global vars within a function in PHP the way you do it in Javascript

Question

I have a function that uses lots of global vars and arrays - e.g.

$a=1;
$b[0]=\'a\';
$b[1]=\'b\';
$c=\'Hello\';

function foo() {
 echo \"$a 
       $b[0] 
              


        

Answer 1

When ever you have a function, the context management in PHP 5.3 doesn't allow access to global variables without the use of the "global" keyword.

Php.net has a post about the topic here.

function foo() {
    global $a, $b, $c;
    echo "$a 
    $b[0] 
    $b[1] 
    $c";
}
