Question

I’ve noticed that when I try to display the value of a variable with PHP, for example using print_r($array)/var_dump(), etc or even when using the Reflection API, I end up with output that is hard to read because there are no line breaks. Every screen shot I see everywhere else has these things displayed in a sort of tree looking format that is much easier to read. Does anyone know why this is?

Answer 1

Try:

echo nl2br($output);

Or try viewing it with the “View source” option of your browser.

Hope this helps

EDIT

OR just use the pre tags, like this:

<?php
function my_print_r($var) {
    $output = "";
    $output .= "<pre>";
    $output .= print_r($var, true);
    $output .= "</pre>";
    return $output;
}


echo my_print_r(array(1, 2, 3));
?>
