把简单的二维数组变成一维数组

在工作中我们经常需要把二维数组变成一维数组。那么就需要循环拿出来,其实有时候我们可以使用一些小技巧,借助php的内置函数来实现,但是我说的只是简单的二维数数组$arr= array('name'=>array('a'=>'abc','b'=>'bcd','c'=>'cde'));如果我们使用array_pop(),就可以拿到一维数组了,array_pop()本来是删除并返回数组的最后一个元素。

所以我们就可以将上诉的$arr变成array('a'=>'abc','b'=>'bcd','c'=>'cde'),这样就把二维数组变成一维数组了,但是仅限于二维数组中是一个一维数组,如果是多个一维数组的话就会返回最后一个数组了。
