如何在PHP中使用多维数组的循环中使用str_replace（）？

Question

I am working with three text files.......

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

and so far I have been able to parse them all into one array. The following output is this......

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

I have to replace all F's in Gender to Female, M's to Male, and the DOB format has to be "/".

Here is the following code I used to parsed the info:

<?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;
    }
}

The following result deletes 'Hingis Martina MF 4-2-1979 Green' and 'Seles Monica HF 12-2-1973 Black'. What would be the best solution to replace them all?

Answer 1

I'd suggest to add two function to do the work. One for renaming/normalizing the gender and one for normalizing the date. And then add a call to each of the function, when you process the data value in the loop. In other words: you iterate over the values, modify them and store them in the final array.

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;
}
