OddOccurrencesInArray.php

function solution($A) {
    // write your code in PHP7.0
    
    $values=array_count_values($A);
    
    foreach($values as $key=>$value){
        if(($value % 2===1)){
            return $key
        }
    }
    
    return null;
}

True... .Nice catch. Thanks, I don't even know why I decided to traverse the entire length of the array.
