Displaying/printing data frame is a common operation during development. It's the easiest way to debug data frame. By default, it will grab the selected number of rows (20 by default)

Example:

<?php 

$output = data_frame()
    ->read(from_())
    ->withEntry('...', ref()->doSomething())
    ->display($limit = 5, $truncate = 0);
    
echo $output;

Output:

+------+--------+---------+---------------------------+-------+------------------------------+--------------------------------------------------------------------------------------------+------------------------------------------------------------------------------------------------+
|   id |  price | deleted | created-at                | phase | items                        | tags                                                                                       | object                                                                                         |

5 rows

Alternatively you can use DataFrame::write function to display data frame:

<?php 

$output = data_frame()
    ->read(from_())
    ->withEntry('...', ref()->doSomething())
    ->write(to_output(truncate: false))
    ->run();
