print_r() : how to display it vertically ?

How to display the result of print_r vertically ?

 

It display like this (horizontal) :

Array ([0] => fruit [1] => animal [2] => machine )

 

I was hoping it would display vertically :

(see the image below) or http://au.php.net/print_r

 

Thanks.

Try this:

 

print "<pre>";
print_r($var);
print "</pre>";

 

The other option is:

 

print nl2br(print_r($var, true));

Thanks. It works!  but it doesn't have indentation.

 

btw why this never been mentioned in the tutorial/doc like http://au.php.net/print_r (they just give print_r while the result on their page is vertical) ?

try this,

echo str_ireplace(array("\n"," "),array('<br>',' '),print_r($arr,true));

it should preserve tab as well

The result IS vertical, when displayed as text.  It's just not vertical when displayed as HTML.  If you view the source of the page, you'll see the formatting which you see in the documentation.

the nl2br version won't indent but pre tags will

 

<?php
$ar = array (
          'abc' => array (1,2,3),
          'def' => array (7,8,9)
        );
        
echo '<pre>', print_r($ar, true), '</pre>';
?>

 

Array
(
    [abc] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
        )

    [def] => Array
        (
            [0] => 7
            [1] => 8
            [2] => 9
        )

)
