Write a function removeDuplicates -PHP( arr) that takes an associative array as a parameter and returns the same associative array except with all duplicate values removed. You may not use the function array_unique for this problem. For example:$arr = array(    'a' => "one",    'b' => "two",    'c' => "three",    'd' => "two",    'e' => "four",    'f' => "five",    'g' => "three",    'h' => "two" ); Expand (10 lines) print_r(removeDuplicates( arr)); Would print: Array (     [a] => one     [e] => four     [f] => five )
