Ravinder,
Please write a PHP function to parse the $color[] array and create the string(2) to append in the badge alert text.
Hint: You need to read a $serialized_badges JSON string (which we will get from the user table and convert it to a PHP array using json_decode() then perhaps a foreach() loop to compare against the current $color[] array.
Or, you can do all this in Javascript by storing the badge[] js array serialized in localstorage, which is how I would do it I think.... No reason to do this in PHP, so I think best to do in Javascript.

if you could give me little more scenario like sample input and expected output then I will try my BEST to write it. Sorry I am that good like you in coding to be honest.Thanks,

3. What is on Your Mind?
I have moved the bug badge out of reserve and into the main stream. Basically, I will assign a color level like the others, based on who has made a good actionable bug report for UNIX.COM. "Good" means screenshots, links, and even details from web dev tools our the HTML source code. So far,... (0 Replies)

ARRAYITERATOR(3) 1 ARRAYITERATOR(3) The ArrayIterator class INTRODUCTION
This iterator allows to unset and modify values and keys while iterating over Arrays and Objects. When you want to iterate over the same array multiple times you need to instantiate ArrayObject and let it create ArrayIterator instances that refer to it either by using foreach or by calling its getIterator() method manually. CLASS SYNOPSIS
ArrayIterator ArrayIteratorArrayAccessSeekableIteratorCountableSerializable Methods o public void ArrayIterator::append (mixed $value) o public void ArrayIterator::asort (void ) o public ArrayIterator::__construct ([mixed $array = array()], [int $flags]) o public int ArrayIterator::count (void ) o public mixed ArrayIterator::current (void ) o public array ArrayIterator::getArrayCopy (void ) o public void ArrayIterator::getFlags (void ) o public mixed ArrayIterator::key (void ) o public void ArrayIterator::ksort (void ) o public void ArrayIterator::natcasesort (void ) o public void ArrayIterator::natsort (void ) o public void ArrayIterator::next (void ) o public void ArrayIterator::offsetExists (string $index) o public mixed ArrayIterator::offsetGet (string $index) o public void ArrayIterator::offsetSet (string $index, string $newval) o public void ArrayIterator::offsetUnset (string $index) o public void ArrayIterator::rewind (void ) o public void ArrayIterator::seek (int $position) o public string ArrayIterator::serialize (void ) o public void ArrayIterator::setFlags (string $flags) o public void ArrayIterator::uasort (string $cmp_function) o public void ArrayIterator::uksort (string $cmp_function) o public string ArrayIterator::unserialize (string $serialized) o public bool ArrayIterator::valid (void ) PHP Documentation Group ARRAYITERATOR(3)
