Echoing Array Contents in PHP

Question:

I have an array with multiple levels of data. How can I display its contents without the array structure?

Code:

$results = [
    'data' => [
        [
            'page_id' => 204725966262837,
            'type' => 'WEBSITE',
        ],
        [
            'page_id' => 163703342377960,
            'type' => 'COMMUNITY',
        ],
    ]
];

// Unsuccessful attempt
foreach ($results as $result) {
    echo $result->type;
    echo "\n";
}

Answer:

To display the contents of an array without its structure, you can use one of the following methods:

1. print_r() and echo:

echo '<pre class="brush:php;toolbar:false">';
print_r($results);
echo '

2. var_dump(): Provides detailed information about the array, including data types and lengths.
3. Foreach Loop: Iterate over the array and echo the desired values.

foreach ($results['data'] as $data) {
    echo $data['type'] . "\n";
}
