Possible to capture PHP echo output?

Question

So I have a function such as:

public static function UnorderedList($items, $field, $view = false){
    if(count($items) > 0){
        echo \'
\'         


        

Answer 1

Very Similar to previous answer but a little more concise for my purposes:

<?php
ob_start(); // Start output buffering

Render::UnorderedList(Class::getItems(), Class::getFields(), true); 

$list = ob_get_clean(); // Store buffer AND cleans it

echo $list; // will contain the contents
?>

I also want to mention how useful this is for PHP unit testing so as not to clutter your test logs with the output of what you are testing unless the test fails. Here is another stackflow answer related to this because I found this answer first on my google search when I was looking at how to test items with echo output : How to use output buffering inside PHPUnit test?

Answer 2

Yes, using output buffering.

<?php
ob_start(); // Start output buffering

Render::UnorderedList(Class::getItems(), Class::getFields(), true); 

$list = ob_get_contents(); // Store buffer in variable

ob_end_clean(); // End buffering and clean up

echo $list; // will contain the contents
 ?>
