Operating system: Windows XP
PHP version: 5.2.5
PHP Bug Type: Variables related
Bug description: Scope/function issue
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
