how to change a class method behavior and output in php

How can I design a pattern that can affect calling methods of a class and getting an output from them, for example when we use return $this we can constantly call multiple methods using pointers but in this approach, we cant affect the previous called method through the last called method..

Instance code :

layout1.php
|--------------|
<div>

 {content}

</div>


index.php 
|-----------|

//return output
$view->layout('layout1')->content('test');

In case the instance code changed to the following

//echo output
$view->layout('layout1');

I need the function to be informed and show a different behavior on sending the output. For instance , in the first code the output value should be returned but in the second one, the value must be directly echoed..

Sample code :

layout1.php
|--------------|
<div>

{content}

</div>


index.php 
|-----------|

$view = view();

//return output
$view->layout('layout1')->content('test');


//echo output
$view->layout('layout1');



 view.php
|-----------|

class view{

 public function layout($file){

  return $this;
 }


 public function content($html){

 return $this;
 }

}

Thank you very much in advance for your help...
