Getting name of array

Given a multi array like this

Code:

 Array

(

    [warranty15] => Array

        (

            [id] => 15 year

            [text] => 15 Years

        )



    [warranty20] => Array

        (

            [id] => 20 year

            [text] => 20 Years

        )



    [warranty25] => Array

        (

            [id] => 25 year

            [text] => 25 Years

        )

}

If I run this code, it prints out the contents of each array.

PHP Code:


		
			
    foreach ($myArray as $key)

    {

      echo $key['id'].' - '.$key['text'].'<br>';

    }

But I need to get the name of those arrays, like warranty15 and warranty20. Would someone please explain how to do that?

PHP Code:


		
			
array_search($key, $myArray);

should do it, haven't tested though.

This should do it for you, amigo:

php Code:

foreach ($myArray as $key => $value)
{
    echo $key . ': ' . $value['id'] . ' - '.$value['text'] . '</br>';
}

That doesn't seem to do it but maybe I missing sometihng obvious. It I run the above, the output is

Quote:

warranty - -

So it got the array name but not the contents of that array. I then thought to try this:

PHP Code:


		
			
    foreach ($myArray as $key)

    {

      echo $key.'<br>';

      foreach ($key as $value)

      echo $key . ' - '. $value['id'].' - '.$value['text'].'<br>';

    }

But it doesn't get the name of the array. The output is

Quote:

Array
Array - 15 year - 15 Years
Array - 20 year - 20 Years
Array - 25 year - 25 Years

Is there a way to have both the array name and its contents printed?

Your example array, in the first post, must not be the exact array that your code is using else Wildhoney's snippet would have worked.

If the array is modified to what I think you might actually be using (based on the post just before this one) then the following code should help:

PHP Code:


		
			
$array = array

(

    'warranty' => array

    (

        'warranty15' => array('id' => '15 year', 'text' => '15 Years'),

        'warranty20' => array('id' => '20 year', 'text' => '20 Years'),

        'warranty25' => array('id' => '25 year', 'text' => '25 Years')

    )

);



foreach ($array as $label => $warranties)

{

    // "warranty"

    echo $label."\n";

    foreach ($warranties as $key => $warranty)

    {

        // e.g. "warranty15 - 15 year - 15 Years<br>"

        echo $key.' - '.$warranty['id'].' - '.$warranty['text']."\n";

    }

}

Which outputs:

warranty
warranty15 - 15 year - 15 Years
warranty20 - 20 year - 20 Years
warranty25 - 25 year - 25 Years

Thanks for the help. I was able to get it working with the revised code.
