PHP数组使用 php_encode 后再使用 JSON.parse 转换成js对象会报错(之前数组中有个值是 json字符串)-PHP Chinese Network Q&A

数组：

Array ( [0] => Array ( [productid] => 2 [cateid] => 4 [title] => 衣 [descr] => 吖吖吖吖吖吖吖吖吖吖吖吖吖吖吖吖吖吖吖吖吖 [num] => 197 [price] => 888.00 [cover] => 7xpizy.com1.z0.glb.clouddn.com/58087fa893aa7 [pics] => {"58087faa67f8b":"7xpizy.com1.z0.glb.clouddn.com\/58087faa67f8b"} [issale] => 1 [saleprice] => 799.00 [ishot] => 1 [istui] => 1 [ison] => 1 [createtime] => 0 ) )

json :

[{"productid":"2","cateid":"4","title":"\u8863","descr":"\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416\u5416","num":"197","price":"888.00","cover":"7xpizy.com1.z0.glb.clouddn.com\/58087fa893aa7","pics":"{\"58087faa67f8b\":\"7xpizy.com1.z0.glb.clouddn.com\\\/58087faa67f8b\"}","issale":"1","saleprice":"799.00","ishot":"1","istui":"0","ison":"1","createtime":"0"}]

数组中的 pics 本来就是json了，然后json_encode后在js中JSON.parse会报错：

Unexpected number in JSON at position 169
