Help me please!!!

[Anon]

For school we have to do some excersises but I don't understand this too much.
For example this one:

1 Draw a christmas tree the user must be able to give in the height by using a form.

 x
xxx

xxxxx
xxxxxxx

If anyone knows please let me know.
Thanks

Assuming $number is the height of the tree...

$x = 1;
for($count=0;$count<$number;$count++)
{
echo "<div align='center'>" . str_repeat("x",$x) . "</div>";
$x+=2;
}

I didn't test it, but I think it works. Tell me if I get an A.
