You can use a loop and implode them and store them -

foreach($yourArray as $key => $array) {
    $yourArray[$key] = implode(',', $array);
}

Or array_map also help -

$new = array_map(function($array) {
    return implode(',', $array);
}, $yourArray);

$newArray = array();
foreach ($array $k => $v) {
    $newArray[$k] = implode(",", $v);
}

If you want to change your existing array,

array_walk($your_array, function(&$v){
    $v = implode(',', $v);
});

If you want a new array,

$new_array = array_map('implode', $your_array,
                 array_fill(0, count($your_array), ',')
             );
