Using syntax highlighting script "beautifier" for source code displayed on wiki pages is nice, but my system receives warning:
PHP Deprecated: Function call_user_method() is deprecated in .../cookbook/beautifier/php/Beautifier/Core.php on line 564
Now, call_user_method() is deprecated as of PHP 4.1.0 and should be replaced by call_user_func. Therefore, one should change Line 564 of Core.php accordingly (cf. PhpDig):
# line 564 was
# $code = call_user_method($this->highlightfile->linkscripts{$category}, $this->highlightfile, $oldword, $this->output_module)
# change it to
$code = call_user_func(array(&$this->highlightfile, $this->highlightfile->linkscripts{$category}), $oldword, $this->output_module)
