如何字符串转换成数组

Question

我怎么能转换成字符串ID

$ids = '8552479333,8552438544,'; 

看起来像一个数组

[ “8552479333”， “8552438544”]

我tryed：

$ids = (explode(",",$ids,-1)); 

但这给了我：

Array ([0] => 8552479333 [1] => 8552438544) 

Answer 1

这是一种非常特别的格式化方法。你可能会错过使用JSON编码程序，让你正在寻找确切的结果：

<?php 
$ids = '8552479333,8552438544,'; 
$string = json_encode(explode(',', $ids, -1)); 
var_dump($string); 

输出显然是：

string(27) "["8552479333","8552438544"]" 

Answer 2

<?php 
$ids = '8552479333,8552438544,'; 
$ids = json_encode(explode(',', $ids, -1)); 
print_r($ids); 
?>
