php - JSON から値を取得する

Question

正しい値を取得するのに苦労しています

私は次のものを取得しようとしています

packages>items 次に ID をループします

{"id":1,"title":"Barnsley","slug":"barnsley","packages":[{"id":1,"title":"Group PACKAGE 1","items" 
 {"id":9,"title":"Guiness","band_a":null,"band_b":null,"band_c":null,"band_d":null,"band_e":null,"band_f":null,"band_g":null,"band_h":null,"band_i":null,"band_j":null,"variations":null},
{"id":10,"title":"John Smith","band_a":null,"band_b":null,"band_c":null,"band_d":null,"band_e":null,"band_f":null,"band_g":null,"band_h":null,"band_i":null,"band_j":null,"variations":null},
{"id":22,"title":"Chicken Cheese and Bacon Melt","band_a":4.5,"band_b":4.75,"band_c":5.0,"band_d":5.25,"band_e":null,"band_f":null,"band_g":null,"band_h":null,"band_i":null,"band_j":null,"variations":null}],"additional_items":null,"event_types":null}]}
