ZF-5465: Fix all spelling, grammar and formatting issues for Zend_Json in the reference guide



I change URL about SoapServer API from http://us.php.net/manual/en/… to http://www.php.net/manual/en/class.soapserver.php on Zend_Json-Server.xml .

Because old address seems to be dead.

Closing as won't fix as there was no progress since more than one year and the documentation has been undertaken a huge change since then.
