遍歷數組，類似物品首先在PHP

Question

Array 
(
[0] => Array 
    (
     [intID] => 3 
     [intVolumeType] => 1 
     [intVolume] => 10 
     [totalVolumes] => 10 
     [intTrack] => 10 
     [intTrackType] => 2 
     [totalTracks] => 10 
    ) 

[1] => Array 
    (
     [intID] => 4 
     [intVolumeType] => 2 
     [intVolume] => 100 
     [totalVolumes] => 200 
     [intTrack] => 111 
     [intTrackType] => 3 
     [totalTracks] => 222 
    ) 

）

我想打印上述陣列：
intVolumeType = 1個
totalVolumes = 10
intVolumeType = 2
totalVolumes = 200

---

intTrackType = 2
totalTracks = 10
intTrackType = 3
totalTracks = 222

如何循環訪問此PHP數組。數組中共有六個元素。這可能會增加高達20打印首卷信息，比追蹤等on.Please幫助

// you have to do it manually
