PHP rename array keys in multidimensional array with array content

You could do something like this...

foreach ($array as $k => $v) {
    $array[$v['listing ID']] = $v;
    unset($array[$k]);
}

Iterate over the array. Add a new element and assign it a key using a value from the current element. Then remove the current element. Or iterate over your array and simply add new elements to some fresh array you've just instantiated.

How to replace key in multidimensional array and maintain order

This function should replace all instances of $oldKey with $newKey.

function replaceKey($subject, $newKey, $oldKey) {

    // if the value is not an array, then you have reached the deepest 
    // point of the branch, so return the value
    if (!is_array($subject)) return $subject;

    $newArray = array(); // empty array to hold copy of subject
    foreach ($subject as $key => $value) {

        // replace the key with the new key only if it is the old key
        $key = ($key === $oldKey) ? $newKey : $key;

        // add the value with the recursive call
        $newArray[$key] = replaceKey($value, $newKey, $oldKey);
    }
    return $newArray;
}

Rename array keys in multidimensional array?

Change the assignment line (line 6) around and make newname dynamic. So something like:

...foreach ($value as $key2 => $value2) {
    $newname = 'new_' . $key2;
    $shop[$key][$newname] = $shop[$key][$key2];
    unset($shop[$key][$key2]);
}...

You could use array_map() to do it.

        'value' => $tag['url']
    );
}, $tags);

$newArray["count"] = $myArray[1];

php recursive key renaming for inner arrays only

function TryRenameChildren(array $array)
{
    if(isset($array['child']))
    {
        $array['child'] = keyprefix($array['name'], 'prefix2', $array['child']);

        foreach($array['child'] as $key => $value)
            if(is_array($value))
                $array['child'][$key] = TryRenameChildren($value);
    }

    return $array;
}

$testArray = TryRenameChildren($testArray);
