How Can I Achieve Pretty Printing of Data Structures in PHP?

Pretty Printing in PHP

When debugging PHP scripts, programmers may yearn for the convenience of Ruby's pretty printer. This tool provides a concise and visually appealing representation of complex data structures. To emulate this functionality in PHP, follow this guide:

Solution:

To mimic Ruby's pretty printer, utilize PHP's print_r function. However, to enhance the visual output, wrap the print_r call within

 tags:</p>
<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><pre class="brush:php;toolbar:false">
    <?php
        print_r($your_array);
    ?>

Copy after login

The

 tag preserves whitespace and line breaks, resulting in a formatted display that makes it easier to navigate and debug complex data structures.
