Use a explode () to break the string into array then create a new array where key will be $valor[0] and value $valor[1]

<?php
$str = '3:2,4:1,5:1';
$arr = explode(',', $str); // transforma a string em array.

$arrN = array();
foreach($arr as $item){
    $valor = explode(':', $item); // quebra o elemento atual em um array com duas posições,
                                     onde o indice zero é a chave e o um o valor em $arrN

    $arrN[$valor[0]] = $valor[1];
}
