Description:
------------
When I run this: 
for ($a=1;$a<10;$a++){
drawstar($a);
}

function drawstar($a){
$txt="*";
for ($ct=0;$ct<$a;$ct++){
echo $txt;
}
echo "\n";
}

I get a printout of the stars. The $txt variable is local to the
function.

If I make $txt global scope to the entire file like below it won't
work. 

$txt="*";

for ($a=1;$a<10;$a++){
drawstar($a);
}

function drawstar($a){
for ($ct=0;$ct<$a;$ct++){
echo $txt;
}
echo "\n";
}


Expected result:
----------------
Variable defined globally should be accessible anywhere.

Actual result:
--------------
Nothing happens
