Print out JSON with multiple arrays

Question

I have this JSON string that has been converted into a PHP array:

Array (
    [textfield] => Array (
        [elements] => Array (
            [0] => Array (
                [type] => textField
            )
        )
        [title] => textfield
    )
    [textarea] => Array (
        [elements] => Array (
            [0] => Array (
                [type] => textArea
            )
        )
        [title] => textarea
    )
) textfield

And I'm trying to loop through it and print out the type and title of each array. This is what I have so far:

foreach($inputs as $key => $jsons) {
    foreach($jsons as $key => $value) {
        echo $value;
    }
}

But that only prints out the title. Note, I do actually need to loop through the array and get all the values because I need to use them, I know I could use print_r to just dump the array but that's not what I need!

See my answer. I'll update it once you show how you need $elements[x]['type']. — Rob W

Here's an easy way... but without seeing more of what you're trying to do, who knows if this will even work.

foreach($json as $key => $value) {
  $elements = $value['elements'];
  foreach($elements as $key => $element) {
    echo "$key = {$element['type']}\n";
  }
  $title = $value['title'];
  echo "$key = $title\n";
}

This prints out the title element, but I also need to print out the type within each element of the elements array.

Updated answer for you.

It's complaining about a String to Array conversion where you echo the $element. Which makes no sense since that should loop through the array correct?

Ah, forgot that $element is an array.. fixed answer.

No problem.. Keep in mind that I have specified $element['type'] in a static manner... which may or may not work for you... but if $element will always have a type-keyed array item, then it should be fine.. just something to be aware of for the future.

foreach($inputs as $key => $jsons) {
    foreach($jsons as $key1 => $value) {
          if( $key1 == "title" ) {
                echo "TITLE :-".$value;
          } else if( is_array($value) {
                foreach($value as $key2 => $value2) {
                     echo "Type :".$value;
                }
          }
     }
}
