[RESOLVED] Scope of a variable

[teguh123]

$item="";
for ($i=0; $i<0 ; $i++)
{
$item .= createAnItem();
}

echo $item

I got $item=""

Now. It looks like, unlike C++, the $item within the for is not the same with the $ item before the for. So when I do echo $item I got the original $item, which is ""

What can I do so that $item within the bracket use the $item outside the braket?

[teguh123]

for ($i=0; $i<0 ; $i++)
{
$item1 = $item1 . "<hello />" ;
}

echo $item1;

I got empty.

Why?

[teguh123]

Oh I see. $i <0.

Stupid me.

Should have been $i < 10;
