php如何获得指定值并且组成新数组

有一个php的ping程序目的是来测试网速和连接情况的,程序和运行的结果如下,现在想把结果取出部分值并组成新数组,如下面的结果,要取得值"50% los","232ms","232ms"."232ms"返回新数组如:"50%,232,232,232",也就是程序运行结果直接返回"50%,232,232,232",而不要那么多ping 程序执行结果

//2个小时...郁闷 本以为三十分可以解决 函数已经给你封装了 你可以自己扩展了 希望尽可能的还是多给点分 好累..

你都已经的到数组了下来就是对数组进行编辑了。按照格式再重新构造新数组不就好了。取出每次执行的数组元素，截取其中需要的部分构造成新的数据就好了。用substr()
