数据库取出来的json问题

Question

[{"id":"9","model":"A2","quantity":1},{"id":"8","model":"A1","quantity":1}]
原本应该是这样的。 

Answer 1

$s = ‘[{"id":"9","model":"A2","quantity":1}]’;
echo html_entity_decode(html_entity_decode($s));[{"id":"9","model":"A2","quantity":1}]你自己在入库时自作多情的做了 htmlentities 编码转换，很自然就不能直接使用了
