/* ----------------------------------------------------------------------------
 * this recipe uses a little trick for highlighting php code
 *   1: replace each php snippet with a placeholder
 *   2: highlight html without php and php snippets apart
 *   3: replace each placeholder with its highlighted php snippet
 * 
 * the trick is not perfect only if the html without php is broken
 * however, in such a case many highlighters get fooled but Chili does not
 * 
 * ---
 * this recipe has been adapted for working with Safari
 * in fact, Safari cannot match more than 101236 characters with a lazy star
