按照该操作，安装了zendloader,但还是不行呢[Zend.loader]
zend_loader.enable=1
zend_loader.disable_licensing=0
zend_loader.obfuscation_level_support=3
zend_loader.license_path=
zend_extension = "D:\wamp\bin\php\php5.3.10\ext\ZendLoader.dll"
phpinfo中的关键信息：PHP Extension 20090626
Zend Extension 220090626
Zend Extension Build API220090626,TS,VC9
注：TS应该是线程安全
问题已解决：
我使用的是wamp，而wamp中的php是TS(即线程安全)，但是zendloader要在NTS（线程不安全）中才能运行，所以重新下载了个php（NTS版本），问题就解决了
