imho we don't need any table of supported functions. the manual tells us all, 
and if a function is not supported we can dynamically query for that.
I would like to see php3 also supported. php-4.0.4pl1 is imho the most used
version.

array_search is not that hard to implement. below are some php3 workarounds I
often use.

  function my_array_push ($array, $new_element) {
    if (function_exists('array_push')) {
      array_push($array,$new_element);
    } else {
      $array[] = $new_element;
    }
    return $array;
  }

  function my_in_array($lookup_value, $lookup_array) {
    if (function_exists('in_array')) {
      if (in_array($lookup_value, $lookup_array)) return true;
    } else {
      reset($lookup_array);
      while (list($key, $value) = each($lookup_array)) {
        if ($value == $lookup_value) return true;
      }
    }

    return false;
  }

////
// returns position of found value in indexed array
  function my_array_position ($array, $value, $case_insensitive = false) {
    if (!is_array($array)) return false;
    for ($i=0; $i < count($array); $i++) {
      if ($array[$i] === $value) return $i;
      if (is_string($value)) {
	if ($case_insensitive) {
	  if (strcasecmp($array[$i], $value) === 0) return $i;
	} else {
	  if (strcmp($array[$i], $value) === 0) return $i;
	}
      }
    }
    return false;
  }

BTW: phpwiki fails on safe_mode on.
plugins cannot be executed without proper 
php_admin_value open_basedir settings.
