Introducing Smarty's print_r

Smarty's print_r is a powerful debugging tool that allows you to easily output the contents of an array or object in a human-readable format. It can be used in a variety of programming languages like PHP, JavaScript, and more.

With print_r, you can quickly inspect the data structure of your variables and ensure that they contain the expected data. This is especially helpful when working with complex data structures, like multidimensional arrays and nested objects.

Syntax

smarty_print_r($variable);

Example

<?php
$my_array = array(
    'username' => 'JohnDoe',
    'email' => 'johndoe@example.com',
    'age' => 30,
    'preferences' => array(
        'color' => 'blue',
        'language' => 'en'
    )
);

smarty_print_r($my_array);
?>

Output

Array
(
    [username] => JohnDoe
    [email] => johndoe@example.com
    [age] => 30
    [preferences] => Array
        (
            [color] => blue
            [language] => en
        )
)

As you can see, print_r outputs the contents of the array in a clear and easy-to-read format. You can quickly see the keys and values of each element in the array, as well as any nested arrays or objects.

Conclusion

In conclusion, Smarty's print_r is a must-have tool for any programmer looking to debug their code and ensure that their data is being stored correctly. By using print_r, you can quickly and easily inspect the structure of your variables and ensure that they contain the expected data.
