Answer 1

You should:

1. check the result of strpos() with !== false.
2. Use $_SERVER['REQUEST_URI'] rather than $_SERVER['PHP_SELF'].
3. Wrap the code inside a function.

Something like this:

<?php
function get_current($name) {
  if (strpos($_SERVER['REQUEST_URI'], $name) !== false)
    echo 'class="current"';
}
?>

<div id="blahblah" style="blahblah">
  <a <?php get_current('biography') ?> href="http://domain.com/folder/biography"><img style="blahblah" src="blahblahblahblah"></a>
  <a <?php get_current('contacts') ?> href="http://domain.com/folder/contacts"><img style="blahblah" src="blahblahblahblah"></a>
  ...
  ...
</div>

Answer 2

if the position is 0, then it will evaluate to FALSE in PHP. You should check the return value specifically, i.e. >= 0.

Answer 3

Instead of strpos(), you could try this:

<?php $current = basename($path, ".php"); ?>

<a href="blahblah"<?php if ($current == 'biographies') echo ' class="current"'; ?> />

$current is the name of the current file, without the .php extension.
