Debug variables in Yii 2

I’ve been working with Yii framework version 2.0 for a few days now, and I find Yii’s Debugger and vardumper function are extremely uncomfortable!

Since for the sake of Simplicity and Quick Development, I’ve created a helper for those who use Yii. You can just call dd($var1, $var2, ….); for dump & die or d($var1, $var2, ….); for dump data.

p/s: Please scroll to the end of this article for sample result.

p/s 2: Those functions work with all PHP version

Installation:

  • Create a file so called functions.php in

/common/config/


  • Paste those code into function.php then save it

<?php
/*
* Code by DangNH
* Date: Apr 4, 2016
*/
 
/**
* Debug function
* d($var);
*/
function d() {
    echo '<pre>';
    for ($i = 0; $i < func_num_args(); $i++) {
        yii\helpers\VarDumper::dump(func_get_arg($i), 10, true);
    }
    echo '</pre>';
}
 
/**
* Debug function with die() after
* dd($var);
*/
function dd() {
    for ($i = 0; $i < func_num_args(); $i++) {
        d(func_get_arg($i));
    }
    die();
}

  • Now, edit bootstrap.php in

/common/config/bootstrap.php


and then add this line of code to the top:

PHP
1
require('functions.php'); &nbsp;//add custom helper functions to the whole application

like so

Voila! Now you can call d($var1, $var2, $varx); for dump or dd($var1, $var2, $varx) for dump then die anywhere in your application!
