To debug in PHP we use
print_r() methos. Laravel provides a function to debug is called
dd(). In this article, we are going to see the differences between these functions.

It stands for Dump and Die. The dd() is a helper function to dump a variable’s contents to the browse. It also stops further script execution. Let’s print user data using
$users = User::all(); dd($users);
The output looks like:
We’re seeing 3 users in array. If we expand one user array, we’ll get output like:
We’ll get user info at attributes or original section.
dump() method like similar to
dd(). But it executes further code. Here’s an example:
$users = User::all(); dump($users); echo "shouts";
It is a built-in function of PHP. The
var_dump() function shows structured information about variables/expressions including its data type and value of the variable. The array and object are explored recursively with values to show their structure.
$users = User::find(1); var_dump($users);
We can see now:
print_r() shows human-readable information about the values with a format presenting keys and elements for arrays and objects.
$users = User::find(1); print_r($users);
But it’s better to use
<pre></pre> to see better view:
That’s all, artisans. Thanks for reading. 🙂
$users = User::find(1); echo "<pre>"; print_r($users); echo "</pre>";
