如何在php中将文件名拆分为数组（key => value）？

I have a generator that create PDF files like this:

我有一个生成PDF文件的生成器：

and upload files into ./files/ folder on server.

并将文件上传到服务器上的./files/文件夹中。

I used below code to get array:

我使用下面的代码来获取数组：

<?php 
$files = glob('files/*.{PDF,pdf}', GLOB_BRACE);
print_r($files);

OutPut:

输出：

Array
(
    [0] => files/035146-761326.PDF
    [1] => files/035150-710753.PDF
    [2] => files/035151-771208.PDF
    [3] => files/035153-718443.PDF
    [4] => files/035158-219299.PDF
    [5] => files/035159-667486.PDF
    [6] => files/035172-113022.PDF
    [7] => files/035180-482460.PDF
    [8] => files/035216-232840.PDF
)

now I wanna splite each file name to user and password. for example if i have file like this:
035180-482460.PDF
I should have:

现在我想把每个文件名分成用户名和密码。例如，如果我有这样的文件：035180-482460.PDF我应该有：

file['user] = 035180;
file['password'] = 482460;

I know, I show foreach (files as key => value) and some stuff to split filename; but I don't know how can I do that? :(

我知道，我显示foreach（文件为key => value）和一些东西来分割文件名;但我不知道怎么办呢？ :(

You can use list and explode:

你可以使用list和explode：

<?php
foreach ($files as $file) {
    $base = basename($file);
    list ($user, $pass) = explode('-', substr($base, 0, strpos($base, '.')));
    // $user would contain 035146
    // $pass would contain 761326
}

First you get the basename (convert files/035146-761326.PDF to 035146-761326.PDF) then you'd use substr and strpos to only return the file name excluding the extension, then explode using - and you get the two parts.

首先你得到基本名称（将文件/ 035146-761326.PDF转换为035146-761326.PDF）然后你使用substr和strpos只返回不包括扩展名的文件名，然后使用 - 爆炸 - 你得到两部分。

array_map is very helpful in such cases:

在这种情况下，array_map非常有用：

$files = array_map(function($name){
  preg_match('#(\d+)-(\d+)#', $name, $matches); //get user and password
  return array(
    'name' => $name,
    'user' => $matches[1],
    'password' => $matches[2]
  );
}, $files);

print_r($files);

Try:

尝试：

<?php 
$files = glob('files/*.{PDF,pdf}', GLOB_BRACE);
print_r($files);
foreach($files as $file) { 
   $file = preg_replace('/\/(?=.*\/)/', ' ',  $file); // it will solve the ./files/ issue which you mentioned in comment
   //  suppose $file is files/035146-761326.PDF
   $arr = explode("/",$file); // it will give array( [0]=>files and [1]=> 035146-761326.PDF)
   $filename = explode(".",$arr[1]); // now split $arr[1] with dot, so will give new array array([0] => "035146-761326", [1] => "pdf")
   $arrname = explode("-",$filename[0]); // now split $filename[0] with - so it will give array ([0]=>035146 , [1] =>761326 )
   echo "username: ".$arrname[0];
   echo "password: ".$arrname[1];
}

?>
