Out of interest, why do you want to do this?
If there isn't a PHP function (there is get_defined_vars() but I don't
think this does what you want) then you could create your own class that
manages variables.
eg.
class CVar {
protected $var_name = '';
protected $var_value = '';
public function __construct( $name = '', $value = '' ) {
$this->var_name = $name;
$this->var_value = $value;
}
public function getName() { return $this->name; }
public function getValue() { return $this->value; }
public function setName($name) { $this->var_name = $name; }
public function setValue($value){ $this->var_value = $value; }
}
function foo($bar) {
return $bat->getName();
}
$myvar = new CVar('animal','dog');
echo foo( &$myvar );
OR something like that....
just curious why ;-)
.... and now someone will point a really easy way to do it and as well
and i'll look a fool... LOL
