 * I’m working in the index.php which calls various other bits in the theme. At 
   the top, to randomize I declare…
 * `srand((double)microtime()*1000000); 
    $randval = rand(0,1);
 * … inside `<?php ?>` section. If I want to use it later on in the same file, I
   can still call `$randvall` without having to declare srand again right?

 * As long as you’re not within a function or something like that, sure. If you’re
   curious about what the value is of $randval somewhere just do `<?php var_dump(
   $randval); ?>`. If it turns out empty, do `<?php global $randval; ?>` before 
   you use it.
