Talking about coffee... your above code could use some. Try this:
<?php
class MyClass
{
function MyVar( $val=null )
{
static $datum;
if( $val === null )
{
return $datum;
}
$datum = $val;
}
}
?>
But also I'd recommend fixing the the problem whereby you
can't set $datum to the null value, otherwise you may run
into unexpected issues down the road.
<?php
class MyClass
{
function MyVar( $val=null, $set=false )
{
static $datum;
if( $set === false )
{
return $datum;
}
$datum = $val;
}
}
?>
Cheers,
Rob.
