Answer 1

可以使用loop和implode它們並把它們存儲 -

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

或者array_map還幫助 -

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

Answer 2

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

Answer 3

如果你想改變你現有的陣列，

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

如果你想要一個新的數組，

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