PHP（WAMP）不像Windows那样对文件进行排序

Question

使用WAMP，我正在尝试使用以下代码使PHP与Windows相同：

<?php
    $folder = opendir("folderx");
    $fileNameList = array();

    while(false !== ($fileName = readdir($folder))){
        array_push($fileNameList, $fileName);
    }

    echo "<pre>";
    print_r($fileNameList);
    echo "</pre>";
?>

然而，我得到了奇怪的结果。这就是PHP的排序方式：

Array
(
[0] => .
[1] => ..
[2] => New Text Document - Copy (2) - Copy - Copy.txt
[3] => New Text Document - Copy (2) - Copy.txt
[4] => New Text Document - Copy (2).txt
[5] => New Text Document - Copy (3) - Copy.txt
[6] => New Text Document - Copy (3).txt
[7] => New Text Document - Copy (4) - Copy.txt
[8] => New Text Document - Copy (4).txt
[9] => New Text Document - Copy - Copy (2) - Copy.txt
[10] => New Text Document - Copy - Copy (2).txt
[11] => New Text Document - Copy - Copy (3).txt
[12] => New Text Document - Copy - Copy - Copy (2).txt
[13] => New Text Document - Copy - Copy - Copy - Copy.txt
[14] => New Text Document - Copy - Copy - Copy.txt
[15] => New Text Document - Copy - Copy.txt
[16] => New Text Document - Copy.txt
[17] => New Text Document.txt
)

这就是Windows的排序方式：

Answer 1

如果使用natcasesort（$ fileNameList）对数组进行排序，如下所示：

<?php
$folder = opendir("folderx");
$fileNameList = array();

while(false !== ($fileName = readdir($folder))){
    array_push($fileNameList, $fileName);
}

function strip_non_cmp_characters($word) {
    return str_replace(array("(",")"," ","."),array("","","",""), $word);
}

function wincmp($a,$b) {
    return strnatcasecmp(strip_non_cmp_characters($a),
        strip_non_cmp_characters($b));
}

usort($fileNameList,"wincmp");

echo "<pre>";
print_r($fileNameList);
echo "</pre>";

您可以使用scandir按字母顺序排序文件。 Opendir会将它们存储在文件系统中，而不是它们在Windows中显示的内容。
