我已经解析了三个不同的文本文件:
space.txt
Kournikova Anna F F 6-3-1975 Red
Hingis Martina M F 4-2-1979 Green
Seles Monica H F 12-2-197
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
我使用以下代码将所有文件解析为一个数组.............
<?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, $pipe_array);
function changeGender($gender) {
if($gender === 'F') {
return str_replace('F', 'Female', $gender);
}
elseif($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" => $data_arr[2],
"gender" => changeGender($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" => $data_arr[2],
"date_of_birth" => normalizeDate($data_arr[4]),
"favorite_color" => $data_arr[3]
];
}
elseif ($name == 'pipe') {
$arr[] = [
"last_name" => $data_arr[0],
"first_name" => $data_arr[1],

];
}
}
return $arr;
}
for ($i=0; $i < count($finalArray); $i++) {
foreach ($finalArray as $key => $row) {
$gender[$key] = $row['gender'];
$last_name[$key] = $row['last_name'];
}
array_multisort($gender, SORT_ASC, $last_name, SORT_ASC, $finalArray);
echo join(' ', $finalArray[$i]) . '<br>';
}
var_dump($finalArray);
?>
现在我有如下数组...........

目前输出为........
Kelly Sue Female 7/12/1959 Pink
Bishop Timothy Male 4/23/1967 Yellow
Abercrombie Neil Male 2/13/1943 Tan
Hingis Martina Female 4/2/1979 Green
Seles Monica Female 12/2/1973 Black
Kournikova Anna Female 6/3/1975 Red
Bonk Radek Male 6/3/1975 Green
Bouillon Francis Male 6/3/1975 Blue
Smith Steve Male 3/3/1985 Red
我想按女性排序然后按男性，然后按last_name asc ........
Hingis Martina Female 4/2/1979 Green
Kelly Sue Female 7/12/1959 Pink
Kournikova Anna Female 6/3/1975 Red
Seles Monica Female 12/2/1973 Black
Abercrombie Neil Male 2/13/1943 Tan
Bishop Timothy Male 4/23/1967 Yellow
Bonk Radek Male 6/3/1975 Green
Bouillon Francis Male 6/3/1975 Blue
Smith Steve Male 3/3/1985 Red
我也试过......
function sortBy($field, &$array, $direction = 'asc') {
usort($array, create_function('
$a, $b', ' $a = $a["' . $field . '"];
$b = $b["' . $field . '"];
if ($a == $b) {
return 0;
}
return ($a ' . ($direction == 'desc' ? '>' : '<') .' $b) ? -1 : 1; '));
return true;
}
for ($i=0; $i < count($finalArray); $i++) {
sortBy('gender', $finalArray);
sortBy('last_name', $finalArray);
echo join(' ', $finalArray[$i]) . '<br>';
}
我已经尝试了array_multisort()， usort()， sort()， asort()，我仍然不能产生我想要的结果。什么解决方案可以用来产生结果?
好吧，我将给出一个带有两个标准的示例，但它没有在您的数据上进行测试。所以下面的compare()函数接收两个数组来比较。怎么做呢?在示例中，每个数组包含两个数字，首先对key = 0的数字进行排序，然后对key = 1的数字进行排序。当然，你的钥匙是不一样的。
function compare($array1,$array2)
{
// numbers at key 0 are equal
if ($array1[0] == $array2[0])
{
// so we look at key 1.
if ($array1[1] == $array2[1]) return 0;
return ($array1[1] < $array2[1]) ? -1 : 1;
}
return ($array1[0] < $array2[0]) ? -1 : 1;
}
$a = [[1,2],[3,4],[5,4],[4,2],[1,8]];
usort($a,'compare');
foreach ($a as $key => $value)
{
echo "<pre>$key: ".print_r($value,TRUE)."'n</pre>";
}
你所需要做的就是使它适应你的情况。
这对数组中的两个值进行排序，正如您所说的，都是升序排序。如果你想让其中一个按降序排列，就把<改成>。这里使用的键是0和1，您的键是gender和last_name。
有些值不能与<比较操作符进行比较，因此您需要使用其他操作符。在last_name的情况下，您可能希望使用strcasecmp()。
代码中的主要问题:
- 您按
'r拆分:最好按'n拆分，它适用于所有平台。但是，由于换行符可以是'r'n，因此还需要删除另一个字符。这可以用trim()来做。所以我建议对所有值应用trim()。 -
changeGender函数看起来很奇怪。你可以使用:return $gender === 'F' ? 'Female' : 'Male'。 - 你可能还想跳过输入中的空行。
- 你在数组上循环排序，这是错误的。外环应该被移除。如果您需要它来列出数据，那么将排序移出它。
更正后的代码(也很好地缩进)后面是我标记为//**的注释:

看它在eval上运行。其中使用您提供的样例数据。
