in php use this function: $dataArray= json_decode (yourjsonarray); then you get all json data to php array in $dataArray. after that u can use that array and put data in sql. if you want to put the whole array in db then you can use function : serialize ($data); and insert in mysql column and later grab from sql and unserialize it using unserialize (yourdata) .. in order to pass to javasript from php through ajax u can again json_encode (yourunserializeddata) and echo it to javascript using ajax
