本文实例讲述了PHP实现的多维数组去重操作。分享给大家供大家参考,具体如下:
最近用到了一个获取历史会议列表的问题,需要去这个多维数组去重后返回返回给客户端,这里使用了几个php的组装函数,分享下,示例代码如下:
运行结果:
num: 10Array ( [0] => Array ( [hostName] => 杨新 [pcode2] => 41675441 [email] => xin.yang@xx.cn [selfName] => 邵兵 ) [1] => Array ( [hostName] => 杨新 [pcode2] => 41675441 [email] => xin.yang@xx.cn [selfName] => 邵兵 ) [2] => Array ( [hostName] => 中信国安科技控股有限公司 [pcode2] => 9730284461 [email] => liuxiao@gakj.xx.com [selfName] => 邵兵 ) [3] => Array ( [hostName] => 中信国安科技控股有限公司 [pcode2] => 9730284461 [email] => liuxiao@gakj.xx.com [selfName] => 邵兵 ) [4] => Array ( [hostName] => 刘惠 [pcode2] => 64068956 [email] => huijie.liu@xx.cn [selfName] => 邵兵 ) [5] => Array ( [hostName] => 刘惠 [pcode2] => 64068956 [email] => huijie.liu@xx.cn [selfName] => 邵兵 ) [6] => Array ( [hostName] => 刘凯南 [pcode2] => 14818360 [email] => kainan.liu_3@xx.cn [selfName] => 邵兵 ) [7] => Array ( [hostName] => 刘凯南 [pcode2] => 14818360 [email] => kainan.liu_3@xx.cn [selfName] => 邵兵 ) [8] => Array ( [hostName] => 宋纬奇 [pcode2] => 62947142 [email] => weiqi.song@xx.cn [selfName] => 邵兵 ) [9] => Array ( [hostName] => 宋纬奇 [pcode2] => 62947142 [email] => weiqi.song@xx.cn [selfName] => 邵兵 ) )

关于php的序列化的确是几年前才使用的技术,目前大家更多的是使用json_encode
,且后者效率也比php的序列化高。
序列化也还是很有用的。上面的例子中主要是函数array_map()
和array_unique()
的结合使用。
希望本文所述对大家PHP程序设计有所帮助。
