PHP的array_filter无钥匙preservation [英] php array_filter without key preservation

问题描述

，如果我筛选具有array_filter阵列以消除空值，键是preserved和阵列中这个生成的洞。例如：

if i filter an array with array_filter to eliminate null values, keys are preserved and this generated "holes" in the array. Eg:

The filtered version of
    [0] => 'foo'
    [1] =>  null
    [2] => 'bar'
is 
    [0] => 'foo'
    [2] => 'bar'

我怎样才能获得，而不是

How can i get, instead

[0] => 'foo'
[1] => 'bar'

？谢谢

推荐答案

您可以使用 array_values​​ 滤波后得到的值。

You could use array_values after filtering to get the values.
