PHP print_r Formatter

Clean up PHP print_r output so arrays and nested values are easier to scan.

print_r output

Formatted output

Array
(
    [name] => Ada
    [roles] => Array
    (
        [0] => admin
        [1] => editor
    )
)

Use this formatter when copied print_r() output is compressed onto one line and hard to read.

PHP example

echo '<pre>';
print_r($value);
echo '</pre>';

print_r() is readable but loses type detail. Use var_dump() or structured logging when types matter.

Does this parse every print_r output?

It formats common inline print_r output and is intended as a quick readability helper.

Should print_r be used in production?

No. Use structured logging and remove direct debug output from production responses.

View PHP serialized data as an indented tree for debugging nested arrays and objects.

Format and validate JSON used with PHP json_decode and json_encode directly in your browser.

Test regular expression patterns against sample text before using preg_match in PHP.
