How many time did you write:
echo '<pre>'; print_r($array); echo '</pre>';
I am quite sure you know what I mean. So I created the debugVar function.
You can install it using composer from command line:
composer require provolik/debugvar
If you want know the content of your var, simply put it in the function, like this:
debugvar($variables);
You can pass to it how many vars you want:
debugvar($var1, $var2, $var3, $var4);
Often you need to show the var and then call a die:
debugvar_die($variables);
In other circumstances, for example in production environment, you need to print a var in hide mode:
debugvar_hide($variables);
And that's all.
