Is there a pretty print for PHP?

Answer 1

    <?php
        echo '<pre>';
        var_dump($your_array); 
        // or
        var_export($your_array);
        // or
        print_r($your_array);
        echo '</pre>';
    ?>

Or Use external libraries like REF: https://github.com/digitalnature/php-ref

Answer 2

Remember to set html_errors = on in php.ini to get pretty printing of var_dump() in combination with xdebug.

Answer 3

For simplicity, print_r() and var_dump() can't be beat. If you want something a little fancier or are dealing with large lists and/or deeply nested data, Krumo will make your life much easier - it provides you with a nicely formatted collapsing/expanding display.

Answer 4

Expanding on @stephen's answer, added a few very minor tweaks for display purposes.

function pp($arr){
    $retStr = '<ul>';
    if (is_array($arr)){
        foreach ($arr as $key=>$val){
            if (is_array($val)){
                $retStr .= '<li>' . $key . ' => array(' . pp($val) . '),</li>';
            }else{
                $retStr .= '<li>' . $key . ' => ' . ($val == '' ? '""' : $val) . ',</li>';
            }
        }
    }
    $retStr .= '</ul>';
    return $retStr;
}

Will format any multidimensional array like so:

Answer 5

This is what i usally use:

$x= array(1,2,3);
echo "<pre>".var_export($x,1)."</pre>";

Answer 6

Both print_r() and var_dump() will output visual representations of objects within PHP.

$arr = array('one' => 1);
print_r($arr);
var_dump($arr);
