如何更新数据库中数组的值

Question

I am retriving following data from the database.When I do print_r , it gives me follwing result.

Array ( [0] => stdClass Object ( [params] => {"size":"980|*|485|*|1","responsive":"1|*|0","align":"normal","autoplay":"1|*|6000" } ) )

Now I want to change the value of autoplay (which is last in this array) in it.How can I do that with the update query ?

NOTE: Field name is param in database and table name is xyz.

Answer 1

As stated, your params is a json object. You need to decode that object so that you can use it.

$data = json_decode($item[0]->params);

$data->autoplay = 'New VALUE';
