如何迭代n深度数组以过滤字符串节点-PHP [英] How to iterate a n-deep array to filter string nodes - PHP

问题描述

如何在字符串节点上迭代多维数组和过滤器?我正在尝试创建一种简单的方法来清理通过POST进入我的应用程序的数据，并认为这真的很方便.

How can I iterate a multidimensional array and filter on string nodes? I'm trying to create an easy way to sanitize data coming into my application via POST and think this would be really handy.

推荐答案

您可以使用递归函数遍历数组并过滤其字符串成分.例如:

You can use a recursive function to traverse the array and filter its string components. For example:

function doFilter($arr) {
    foreach ($arr as $key => $value) {
        if (is_string($value)) {
            $arr[$Key] = sanitize($value);
        } else if (is_array($value)) {
            $arr[$key] = doFilter($value);
        }
    }
    return $arr;
}

function sanitize($str) {
    // Perform necessary steps to sanitize $str
    return $str;
}
