PHP - Extract - 使用set键和提取的变量循环多维数组

Question

我每月从用户数据的日志文件中提取数据。代码本身有效，但似乎不优雅。我正在寻找有关如何消除它的想法。感谢任何帮助。

我有以下代码。 data_manip函数在get_files中调用，它将每个月的相关数据分配到一个名为file_resource的数组中。然后调用函数data_manip，它使用＆＃39; extract＆＃39;根据get_files函数中月份名称定义的键名来定义带有$ names的数组。然后，我根据放在数据文件夹中的文件（我没有包含的代码）确定该变量是否存在。 data_analytic函数分析数据并将结果输出到html页面。目前这个解决方案似乎很笨拙。

我想要做的是确定每个月名称变量是否存在（1月 - 12月），然后如果每次查询验证为真，则爆炸与该特定月份名称对应的数组$ name的结果并将结果分配给一个新的数据数组，称为$ january_data，或$ february_data等。

function get_files($month_names){ 
                foreach ($month_names as $month_name) { 
                    $file_resource[] = array(
                        $month_name => 
                            file("data/$month_name.log")
                        );
                }
                data_manip($file_resource);
                return $file_resource;
            }

    function data_manip($file_resource){
                foreach ($file_resource as $month_data) {
