我需要按字母顺序排列以下数组(在所有级别),但asort
似乎不起作用,因为我在函数中有一个递归调用(或者我认为);它只是对我的数组进行了部分排序,因此我将使用按字母顺序排列的数据块,但它们将会出现故障。
帮助!
实施例。目录列表:
apartments.html
js/
application.js
jquery.js
something.js
css/
reset.css
master.css
preview.html
ab_restaurant_at_the_end_of_the_universe.jpg
期望的输出:
array() {
[0] => string() "ab_restaurant_at_the_end_of_the_universe.jpg"
[1] => string() "apartments.html"
["css"] => array() {
[0] => string() "master.css"
[1] => string() "reset.css"
}
["js"] => array() {
[0] => string() "application.js"
[1] => string() "jquery.js"
[2] => string() "something.js"
}
[2] => string() "preview.html"
}
function directory_list($directory) {
$files = array();
if (is_dir($directory)) {
if ($curr_dir = opendir($directory)) {
while (false !== ($file = readdir($curr_dir))) {
if ($file != "." && $file != ".." && $file != "apartment" && $file != "blog") {
if (is_dir($directory. "/" . $file)) {
$files[$file] = directory_list($directory. "/" . $file);
} else {
$files[] = $file;
}
}
}
closedir($curr_dir);
}
}
//asort($files); <-- doesn't work; sorts, but interrupts itself because of self-referencing call above (I think)
return $files;
}
答案 0 :(得分:1)
如果您将$files[] = $file;
更改为$files[$file] = $file;
,那么您可以在尝试使用asort()的地方使用ksort()
