PHP extension Development Call Dynamic Library compilation, can not be found in phpinfo, and cannot call function

PHP extension Development calls the dynamic Library compilation, can no longer be found in the phpinfo, and cannot call the function
RT, through the http://blog.csdn.net/wzhwho/article/details/6949297 this blog implemented a call to Dynamic library extension. I started experimenting with C calling the extension library and running successfully, but after the PHP extension call and compile, PHP cannot load. I beg you to help us greatly

Make sure that the extension you installed is successful
