How to display the key of key array in PHP?

This is the content of $records enter image description here

If I wanted to display the "key" of this key array, how to code?

e.g. in first round of foreach loop I like to display 1 (key), 1 (id), 10 (price) and so on. I would use $record['id'], $record['price'], but I don't know what to code to display the key?

<?php
foreach ($records as $record) {
    foreach ($record as $key => $value) {
        echo $value . '(' . $key . ')';
    }
}
?>

foreach($records as $key=>$record){
  echo "key: ".$key."</br>";
  echo "ID: ".$record['id']."</br>";
  echo "Price: ".$record['price']."</br>";
}

foreach($records as $key => $record) {
  echo $key . '(key), ' . $record['id'] . '(id), ' . $record['price'] . '(price)';
}

foreach ($records as $key => $record) {
    echo $key;
}

Check foreach in PHP manual for more info: http://php.net/manual/en/control-structures.foreach.php

Have you tried to use a foreach ?

foreach($records as $key => $value) {
     echo "Current key: ".$key."<br />";
     print_r($value);
}
