在变量中存储MySQL fetch_assoc（）

Question

If I have something like $data = getSomeData();

which is an associative array, and then I use things like $data['username'] and $data['id'] and so on, will it have to call getSomeData(); every time I use something from the array?

Answer 1

no, the results of getSomeData() are stored in $data, so you are using the values in $data.
