Is it possible to add the output of print() to a variable?
I have the following situation:
I have a php file which looks something like this:
title.php
<?php
$content = '<h1>Page heading</h1>';
print($content);
I have a php file which looks like this:
page.php
<?php
$content = '<div id="top"></div>';
$content.= $this->renderHtml('title.php');
print($content);
I have a function renderHtml():
public function renderHtml($name) {
$path = SITE_PATH . '/application/views/' . $name;
if (file_exists($path) == false) {
throw new Exception('View not found in '. $path);
return false;
}
require($path);
}
When I dump the content variable in page.php it doesn't contain the content of title.php. The content of title.php is just printed when it is called instead of added to the variable.
I hope it is clear what I am trying to do. If not I'm sorry and please tell me what you need to know. :)
Thanks for all your help!
PS
I have found that there was already a question like mine. But it was regarding the Zend FW.
How to capture a Zend view output instead of actually outputting it
However I think this is exactly what I want to do.
How should I setup the function so that it behaves like that?
EDIT
Just wanted to share the final solution:
public function renderHtml($name) {
$path = SITE_PATH . '/application/views/' . $name;
if (file_exists($path) == false) {
throw new Exception('View not found in '. $path);
return false;
}
ob_start();
require($path);
$output = ob_get_clean();
return $output;
}

You can capture output with the ob_start() and ob_get_clean() functions:
ob_start();
print("abc");
$output = ob_get_clean();
// $output contains everything outputed between ob_start() and ob_get_clean()
Alternatively, note that you can also return values from an included file, like from functions:
a.php:
return "<html>";
b.php:
$html = include "a.php"; // $html will contain "<html>"
You can use output buffering to capture any output send ob_start() http://us3.php.net/ob_start. You capture the output with ob_get_flush() http://us3.php.net/manual/en/function.ob-get-flush.php.
Or you could just return the output from title.php like so:
<?php
$content = '<h1>Page heading</h1>';
return $content;
