从json_encode嵌套数组php中的镯子中删除双引号

Question

我有这样的数组

datasets:[{"label":"admin ",  
"backgroundColor":"#FF6384",
"data":"[0,0,3,30,53,6,0,0,54,0,0,6]"},
{"label":"user1",
"backgroundColor":"#FF6384",
"data":"[0,20,0,3,0,0,5,20,30,0,5,0]"}],

我想从数据数组中删除双引号
我想更改为

datasets:[{"label":"admin ",  
"backgroundColor":"#FF6384",
"data":[0,0,3,30,53,6,0,0,54,0,0,6]},
{"label":"user1",
"backgroundColor":"#FF6384",
"data":[0,20,0,3,0,0,5,20,30,0,5,0]}],

Answer 1

也使用RegEx，但仅在data键上进行编辑：

// Assuming your data string as $json
$json = preg_replace('/"data":"(\[[0-9,]*\])"/', '"data":$1', $json);

// Output to verify
echo '<pre>' . print_r(json_decode($json, true), true) . '</pre>';

Answer 2

不太优雅，但在功能上

preg_replace("/\"(\[.*\])\"/", "$1", $Json);

$1是包含[something]的字符串。
