[PHP] References to a variable and scope

[Cesar D. Rodas]

Hello,

I know that PHP doesn't support pointers to a variable, instead of that
there is references to a variable which are similar to pointers, right?

BTW, what I want to do is to save a references to a variable and read the
content when I need, similar to PDO "bindParam". I will try to explain
better in the following pseudo php code.

function foo($a) {
       $GLOBALS['references']['a'] = /*references to $a */
}

function bar() {
      echo $GLOBALS['references']['a'];
}

$var="hello"
foo($var);
$var = "hi";
bar(); /* it should print "hi" instead of "hello" */
