如何在 PHP 中的多维数组循环中使用 str_replace()？

Question

我正在处理三个文本文件......

space.txt

Kournikova Anna F F 6-3-1975 Red
Hingis Martina M F 4-2-1979 Green
Seles Monica H F 12-2-1973 Black

comma.txt

Abercrombie, Neil, Male, Tan, 2/13/1943
Bishop, Timothy, Male, Yellow, 4/23/1967
Kelly, Sue, Female, Pink, 7/12/1959

pipe.txt

Smith | Steve | D | M | Red | 3-3-1985
Bonk | Radek | S | M | Green | 6-3-1975
Bouillon | Francis | G | M | Blue | 6-3-1975

到目前为止，我已经能够将它们全部解析到一个数组中。下面的输出是这样的……

Last_name, First_name, Middle_Initial, Gender, DOB, Fav_color
Kournikova Anna F F 6-3-1975 Red
Hingis Martina M F 4-2-1979 Green
Seles Monica H F 12-2-1973 Black
Abercrombie Neil Male Tan 2/13/1943
Bishop Timothy Male Yellow 4/23/1967
Kelly Sue Female Pink 7/12/1959
Smith Steve D M Red 3-3-1985
Bonk Radek S M Green 6-3-1975
Bouillon Francis G M Blue 6-3-1975

我必须将 Gender 中的所有 F 替换为 Female，将 M 替换为 Male，并且 DOB 格式必须为“/”。

下面是我用来解析信息的代码：

<?php
$space_txt = './data/input/space.txt';
$comma_txt = './data/input/comma.txt';
$pipe_txt = './data/input/pipe.txt';

$parsed_space_data = file_get_contents($space_txt);
$parsed_comma_data = file_get_contents($comma_txt);
$parsed_pipe_data = file_get_contents($pipe_txt);

$space_array = myExpldeLoopFunc('space', ' ', $parsed_space_data);
$comma_array = myExpldeLoopFunc('comma', ',', $parsed_comma_data);
$pipe_array = myExpldeLoopFunc('pipe', ' | ', $parsed_pipe_data);

$finalArray = array_merge($space_array, $comma_array, $pipe_array);

function myExpldeLoopFunc($name, $sep, $data)
{
    $parsedData = explode("\r", $data);

    $arr = [];

    foreach ($parsedData as $data)  {
        $data_arr = explode($sep, $data);

        if ($name == 'space') {
            $arr[] = [
            'last_name' => $data_arr[0],
            'first_name' => $data_arr[1],
            'middle_initial' => $data_arr[2],
            'gender' => $data_arr[3],
            'date_of_birth' => $data_arr[4],
            'favorite_color' => $data_arr[5],

            ];

            if ($data_arr[3] == 'F') {
                return str_replace('F', 'Female', $arr);
            } elseif ($name == 'comma') {
                $arr[] = [
                'last_name' => $data_arr[0],
                'first_name' => $data_arr[1],
                'gender' => $data_arr[2],
                'date_of_birth' => $data_arr[3],
                'favorite_color' => $data_arr[4],

                ];
            } elseif ($name == 'pipe') {
                $arr[] = [
                'last_name' => $data_arr[0],
                'first_name' => $data_arr[1],
                'middle_initial' => $data_arr[2],
                'gender' => $data_arr[3],
                'favorite_color' => $data_arr[4],
                'date_of_birth' => $data_arr[5],

                ];
            }
        }

        return $arr;
    }
}

以下结果删除'Hingis Martina M F 4-2-1979 Green'和'Seles Monica H F 12-2-1973 Black'。将它们全部替换的最佳解决方案是什么？

我建议添加两个函数来完成这项工作。一个用于 renaming/normalizing 性别，一个用于标准化日期。然后在循环中处理数据值时，添加对每个函数的调用。换句话说：您遍历这些值，修改它们并将它们存储在最终数组中。

function renameGender($gender)
{
    if ($gender === 'F') {
        return str_replace('F', 'Female', $gender);
    }
    if ($gender === 'M') {
        return str_replace('M', 'Male', $gender);
    }
}

function normalizeDate($date)
{
    return str_replace('-', '/', $date);
}

function myExpldeLoopFunc($name, $sep, $data)
{
    $parsedData = explode("\r", $data);

    $arr = [];

    foreach ($parsedData as $data) {

        $data_arr = explode($sep, $data);

        if ($name == 'space') {

            $arr[] = [
                "last_name"      => $data_arr[0],
                "first_name"     => $data_arr[1],
                "middle_initial" => $data_arr[2],
                "gender"         => renameGender($data_arr[3]),
                "date_of_birth"  => normalizeDate($data_arr[4]),
                "favorite_color" => $data_arr[5]
            ];

        } elseif ($name == 'comma') {

            $arr[] = [
                "last_name"      => $data_arr[0],
                "first_name"     => $data_arr[1],
                "gender"         => renameGender($data_arr[2]),
                "date_of_birth"  => normalizeDate($data_arr[3]),
                "favorite_color" => $data_arr[4]
            ];

        } elseif ($name == 'pipe') {
            $arr[] = [
                "last_name"      => $data_arr[0],
                "first_name"     => $data_arr[1],
                "middle_initial" => $data_arr[2],
                "gender"         => renameGender($data_arr[3]),
                "favorite_color" => $data_arr[4],
                "date_of_birth"  => normalizeDate($data_arr[5])
            ];
        }
    }

    return $arr;
}
