Display an array in a readable/hierarchical format

Question

Here is the code for pulling the data for my array

Answer 1

I assume one uses print_r for debugging. I would then suggest using libraries like Kint. This allows displaying big arrays in a readable format:

$data = [['Natural Child 1', 'Natural Child 2', 'Natural Child 3']];
Kint::dump($data, $_SERVER);

Answer 2

Instead of

print_r($data);

try

print "<pre>";
print_r($data);
print "</pre>";

Answer 3

This tries to improve print_r() output formatting in console applications:

function pretty_printr($array) {

  $string = print_r($array, TRUE);

  foreach (preg_split("/((\r?\n)|(\r\n?))/", $string) as $line) {

    $trimmed_line = trim($line);

    // Skip useless lines.
    if (!$trimmed_line || $trimmed_line === '(' || $trimmed_line === ')' || $trimmed_line === 'Array') {
      continue;
    }

    // Improve lines ending with empty values.
    if (substr_compare($trimmed_line, '=>', -2) === 0) {
      $line .=  "''";
    }

    print $line . PHP_EOL;
  }
}

Example:

[activity_score] => 0
[allow_organisation_contact] => 1
[cover_media] => Array
        [image] => Array
                [url] => ''
        [video] => Array
                [url] => ''
                [oembed_html] => ''
        [thumb] => Array
                [url] => ''
[created_at] => 2019-06-25T09:50:22+02:00
[description] => example description
[state] => published
[fundraiser_type] => anniversary
[end_date] => 2019-09-25
[event] => Array
[goal] => Array
        [cents] => 40000
        [currency] => EUR
[id] => 37798
[your_reference] => ''

Answer 4

print("<pre>".print_r($data,true)."</pre>");

Answer 5

foreach($array as $v) echo $v, PHP_EOL;

UPDATE: A more sophisticated solution would be:

 $test = [
    'key1' => 'val1',
    'key2' => 'val2',
    'key3' => [
        'subkey1' => 'subval1',
        'subkey2' => 'subval2',
        'subkey3' => [
            'subsubkey1' => 'subsubval1',
            'subsubkey2' => 'subsubval2',
        ],
    ],
];
function printArray($arr, $pad = 0, $padStr = "\t") {
    $outerPad = $pad;
    $innerPad = $pad + 1;
    $out = '[' . PHP_EOL;
    foreach ($arr as $k => $v) {
        if (is_array($v)) {
            $out .= str_repeat($padStr, $innerPad) . $k . ' => ' . printArray($v, $innerPad) . PHP_EOL;
        } else {
            $out .= str_repeat($padStr, $innerPad) . $k . ' => ' . $v;
            $out .= PHP_EOL;
        }
    }
    $out .= str_repeat($padStr, $outerPad) . ']';
    return $out;
}

echo printArray($test);

This prints out:

    [
        key1 => val1
        key2 => val2
        key3 => [
            subkey1 => subval1
            subkey2 => subval2
            subkey3 => [
                subsubkey1 => subsubval1
                subsubkey2 => subsubval2
            ]
        ]
    ]

Answer 6

One-liner for a quick-and-easy JSON representation:

    echo json_encode($data, JSON_PRETTY_PRINT);

If using composer for the project already, require symfony/yaml and:

    echo Yaml::dump($data);
