可以用正則
$jsonStr = '{"db":"[{"0":"9","id":"9"},{"0":"9","id":"9"},]"}'; $jsonStr = preg_replace('/[\'"](\[.*?\])[\'"]/iU', '$1', $jsonStr);// 去除json串中，數(shù)組外的引號，將形如"[{...}]"替換成[{...}]$jsonStr = preg_replace('/,\s*\]/', ']', $jsonStr);// 去除json串中多余的逗號 |
字符串替換：
$jsonStr = str_replace('"[', '[', $jsonStr);$jsonStr = str_replace(',]"', ']', $jsonStr); |

$raw = '{"db":"[{"0":"9","id":"9"},{"0":"9","id":"9"},]"}';
$obj = @json_decode($raw, TRUE);
$obj['db'] = @json_decode($obj['db'], TRUE);
$i_want = @json_encode($obj);
