Laravel dd() vs dump() vs var_dump() vs print_r() with Example
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.
Table of Contents
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:
$users = User::find(1); echo "<pre>"; print_r($users); echo "</pre>";
That’s all, artisans. Thanks for reading.
