How do I use PHP to splice HTML and output it?

Php

demo01.php public static function Buildfullpage () {$data = [' type ' = ' header '                                ], [' type ' = ' companys ', ' com_id ' = ' Beijing ',                Define a lot of variables each content layout is the same]], [' type ' = ' companys ',                ' com_id ' = ' Shanghai ',]], [' type ' = ' companys ', ' com_id ' = ' Shenzhen ', '], [' type ' = ' companys ', ' com_        id ' = ' hangzhou ',]], [' type ' = ' footer ']; foreach ($data as $type = $type _value) {switch ($type) {case ' header ': Echo                Demo01::buildheader ();                Case ' companys ': Echo demo01::buildcom ($data);                Case ' footer ':    Echo Demo01::buildfooter (); }        }    }

Page approximate layout is a header four content (that is, each content is a company's introduction, the template is the same), a footer, in this way, each time just display a content, if you want to show all, how to do?

//index.php
