Re: Variables

Hi Julio,
I have 4 suggestions:
i. Perform the sizeof() operation once and outside
the loop. This will save you some cpu cycles. Also,
if you know for sure that sizeof($artist) is unlikely
to change, set it as a constant.

ii. Create the $c.x string prior to assigning a value
to the variable it represents.
eg.
$artist_size=sizeof($artist);
for($count = 0; $count<$artist_size; $count++)
$varname = "c".($count+1); //
${$varname} = $artist[$count];
}
echo $c1.$c2.$c10;

iii. Go here for more notes on how to create variable variables:
http://www.php.net/manual/en/language.variables.variable.php

iv. Have lots of fun.

cheers!
Kwab
