Status: Bogus
Bug Type: *General Issues
Operating System: WIN98/APACHE1.3.19
PHP Version: 4.0.4pl1
New Comment:
no way, default values are evaluated at compile time
and there is no $foo set at all as the program didn't
start to run by that time
what you want to do is something like
function showvar ( $bar = NULL ) {
if ( $bar === NULL ) {
$bar = $GLOBALS['foo'];
}
echo $bar;
}

why is that? I really need this:(
Will a later version of php support constructions like this?

Shouldn't. Default values must be constant expressions.
Not a bug, bogusified.

<?php
$foo = 'foo';
function showvar( $bar = $foo )
{
//global $foo
//doesn't work either
echo $bar;
}
showvar();
showvar('bar');
?>
gives me a parse error on line 3:(
also:
<?php
$foo = 'foo';
function returnvar()
{
global $foo;
return $foo;
}
function whatisvar( $bar = returnvar() )
{
echo $bar;
}
?>
gives me this:
Parse error: parse error, expecting `')'' in c:/path/to/script/test.php on line 9
Should work, shouldn't it?
