Question

Hello friends I am running 2 applications on the same server and I wanted to import some content of Application-1 into Application-2 and similarly some content of Application-2 into Application-2.

Currently this is how I am getting it:

<?php
    $app1 = file_get_contents('http://localhost/cms');

    file_put_contents('cms.html', $app1); 

    $app2 = file_get_contents('http://localhost/blog');

    file_put_contents('blog.html', $app2); 
?>

Like this I am saving these 2 files with the HTML of those applications

Now lets say I have

a <div id="header"> in cms.html which I want to import in <div id="header"> of Application-2’s index.php file

and

a <div id="footer"> in blog.htmlwhich I want in <div id="footer"> of Application-1’s index.php file.

How do I do this?

UPDATE : Both applications are Joomla and WordPress.

My Template is a simple one without any JavaScript so kindly suggest a PHP solution until and unless it is compulsory to load JavaScript, I want to keep it simple and light.

Please also note I have just started learning programing hence It will be very difficult for me to understand too technical a language hence requesting a simple language. Hope you understand.

If my approach is wrong at the very first place, then please feel free to suggest a better method of doing this task.

Kindly help.

UPDATE 2 : Please not my issue is not of getting content from the other application. My issue is to get a fragment of the HTML file that is being generated.

Well I guess I found a better way of doing it myself so I am posting here as an answer for the sake of others who are looking for a similar solution.

Write a class which will read between the markers and get that bit.

<?Php
class className {
    private $_content;
    private $_Top;
    private $_Bottom;

    public function __construct(
        $url, $markerStartTop = null, 
        $markerEndTop = null, 
        $markerStartBottom = null, 
        $markerEndBottom = null){

            $this->_content = file_get_contents($url);
            $this->_renderTop($markerStartTop, $markerEndTop);
            $this->_renderBottom($markerStartBottom, $markerEndBottom);
        }

    public function renderTop($markerStart = null, $markerEnd = null){
        return $this->_Top;
        }

    private function _renderTop($markerStart = null, $markerEnd = null){
        $markerStart = (is_null($markerStart)) ? '<!– Start Top Block –>' : (string)$markerStart;
        $markerEnd = (is_null($markerEnd)) ? '<!– End Top Block –>' : (string)$markerEnd;

        $TopStart = stripos($this->_content, $markerStart);
        $TopEnd = stripos($this->_content, $markerEnd);

        $this->_Top = substr($this->_content, $TopStart, $TopEnd-$TopStart);
        }

    public function renderBottom(){
        return $this->_Bottom;
        }

    private function _renderBottom($markerStart = null, $markerEnd = null){ 
        $markerStart = (is_null($markerStart)) ? '<!– Start Bottom Block –>' : (string)$markerStart;
        $markerEnd = (is_null($markerEnd)) ? '<!– End Bottom Block –>' : (string)$markerEnd;

        $BottomStart = stripos($this->_content, $markerStart);
        $BottomEnd = stripos($this->_content, $markerEnd);

        $this->_Bottom = substr($this->_content, $BottomStart, $BottomEnd-$BottomStart);
        }
}
?>

Call it:

<?php
    $parts = new className('url/to/the/application');
    echo $parts->renderTop();
?>

This method is fetching exactly the fragment of the content which you marked between the desired markers.
