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:$arr = array( 'a' => "one", 'b' => "two", 'c' => "three", 'd' => "two", 'e' => "four", 'f' => "five", 'g' => "three", 'h' => "two" ); Expand (10 lines) print_r(removeDuplicates(arr));Would print:Array ( [a] => one [e] => four [f] => five ) ```php```This is a basic PHP code snippet intended to define a function named `removeDuplicates`. This function takes one parameter, `$arr`, which is expected to be an array. The function currently has no implementation in its body, indicated by the empty block between the curly braces. To complete this function, you would need to add logic that processes the input array and removes duplicate values.
