Parsing JSON in PHP to extract individual array values

Recently delving into PHP, I encountered a JSON file that I successfully decoded and stored as shown below:

$jsonInput = '[{"b_pag_bo_id":"31","b_pag_user_id":"1","b_pag_id":"1","b_page_mark":"1","b_pag_num":"3","b_pag_note":"","b_page_stop":"1"},{"b_pag_bo_id":"31","b_pag_user_id":"1","b_pag_id":"2","b_page_mark":"1","b_pag_num":"57","b_pag_note":"","b_page_stop":"1"},{"b_pag_bo_id":"31","b_pag_user_id":"1","b_pag_id":"3","b_page_mark":"1","b_pag_num":"60","b_pag_note":"","b_page_stop":"1"},{"b_pag_bo_id":"32","b_pag_user_id":"1","b_pag_id":"4","b_page_mark":"1","b_pag_num":"4","b_pag_note":"","b_page_stop":"1"},{"b_pag_bo_id":"32","b_pag_user_id":"1","b_pag_id":"5","b_page_mark":"1","b_pag_nu...
$decoded = json_decode($jsonInput, true);

print_r($decoded);

I am now seeking guidance on how to extract each value corresponding to different keys such as b_pag_bo_id. How can I achieve this task efficiently?

phpjson

Answer №1

If you want to display data in this way, you can use the following code snippet:

foreach ($decoded as $key => $value) {
    echo $value['b_pag_bo_id'];
}

Answer №2

Implement a foreach loop to iterate through the result and save each piece of data in separate variables.

foreach ( $decoded AS $index => $value ) {
  ${'variable'.$index} = $value;
}

Answer №3

To iterate through the array, you can use a loop like this:

$book_page_ids = array();
$user_ids = array();
foreach ($decoded_array as $element) {
    $book_page_ids[] = $element['b_pag_bo_id'];
    $user_ids[] = $element['b_pag_user_id'];
}

Answer №4

for each item in the playerCredentials array, display key and value pairs using a printf statement inside a loop.
