Couple of convenience methods to add to your bootstrap.php

Although most of the convenience methods will be removed from CakePHP going forward (see the note about basics.php), and I say good riddance, you still have the opportunity to add your own to bootstrap.php.

For example a couple that I like are wrappers for var_dump(). The main reason being is that var_dump() will properly display NULL and FALSE. Unlike debug() and pr() (alias to) print_r(), which will show… well… nothing.

So here you go:

function vd($var) {
  if(Configure::read() > 0) {
    echo '<pre>';
      echo var_dump($var);
    echo '</pre>';
  }
}

Or, if you’d like to die() out:

function vdd($var) {
  if(Configure::read() > 0) {    
      die(var_dump($var));
  }
}

  1. function vd($var) {
    if (Configure::read() > 0) {
    foreach($var as $a => $b) {
    echo $a;
    if(is_array($b)) {
    vd($b);
    } else {
    echo $b;
    }
    }
    }
    }

  2. I think there is a small mistake in the vdd function. The close tag for pre will never occur because is after die().
    In this way it works fine.

    function vdd($var) {
    if(Configure::read() > 0) {
    echo '

    ';
        var_dump($var);
        echo '

    ';
    die(); // or exit;
    }
    }

    Anyway is not a relevant mistake. You make a great job.

    LOL, Duh… very good point :) Anyways in that case the pre tags are not really needed anyway. I’ve just simplified the function a little. But your suggestions is just as good.

    Thanks for sharing.

    1. The wrapper functions may save you a few keystrokes, or many if you use them often, but they slow down execution. Using a wrapper function inside of your own function saves you a few keystrokes one time only. Just type the full function name…

    Exactly, that’s why they are being removed from the usage inside the core. However, when developing they are simply short-cuts and in case of someone accidentally forgetting to remove print_r() in production, can actually quite valuable.

    Same problem, doesn’t properly display certain values.

    A side note, it is actually quite nice to implement a solution like: http://krumo.sourceforge.net/
    (Hmm… I should probably do an example for cake…)
