这篇文章主要介绍了PHP递归删除多维数组中的某个值,需要的朋友可以参考下
今天在做业务逻辑的过程中,需要在一个不确定的多维数组中删除某个特定的key,查了挺长时间加上自己的修改,终于满足了业务逻辑,该方法在修改后应该可以适用于很多地方,所以记录下来以备后用,我这里是一个多维数组,还是json_encode后的,主要目的是删除所有old_tags_id数组中有tag_id=264的数据,顺便要删除相应的tag_name,还有 addtag要减1,,代码如下:
先放递归函数,当然这里是核心,很多人看了这个应该就已经知道如何使用了.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |

维数组长这样,还是jeson_encode后的格式:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 |
