Best way to debug an array using PHP
Every PHP developer should have a function for this. My function is below:
function r($var){ echo '<pre>'; print_r($var); echo '</pre>';}To nicely print data, just call r($data);. If you want more detail, you could use this function:
function d($var){ echo '<pre>'; var_dump($var); echo '</pre>';}
here's mine...
demo: http://o-0.me/dump_r/
repo: https://github.com/leeoniya/dump_r.php
composer: https://packagist.org/packages/leeoniya/dump-r
you can restyle it via css if needed.
Everyone suggests print_r which is in core and works really well.But when it comes to view a large array, print_r() drives me nuts narrowing down the output.
Give a try to krumo.It nicely prints the array with visual formatting, click-expand and it also gives you the exact array key call that you can simply copy and paste.
<?php krumo($my_array);?>Itroubs mentioned Kint as a better alternative to Krumo. (Thanks ITroubs!)
