Install ZendOptimizer extension for PHP5.3 and above, install zend_PHP tutorial for php5.3

Many PHP programs now require ZendOptimizer environment, but ZendOptimizer has been supported after PHP5.2, then No matter what, Zend will not do this. It turns out that starting from PHP5.3, ZendOptimizer has been officially changed to Zend Guard Loader.
