PHP - 爆炸/移动/文件名 [英] PHP - Exploding / Moving / Filename

问题描述

不知道你能否帮帮忙，我是新来的PHP和我坚持。我有文件加载看起来像这样的：

Wonder if you can help, i'm new to php and am stuck. I have loads of files that look like this:

2014年4月1日NS122345 - 日期，该人的声母和员工有code。

2014-04-01 NS122345 - The date, the initials of the person and there employee code.

我希望能够有NS或JB或Ga的文件移动到有相关文件夹/目录。因此，对于NS它将进入弥敦道桑德斯文件夹中，JB到乔·贝利文件夹。

I want to be able to move the files that have NS or JB Or GA into there relevant folder/directories. So for NS it would go into the Nathan Saunders Folder, for JB into the Joe Bailey folder.

一个少数人对我说使用爆炸和SUBSTR了拆分文件名，然后我想通过数组搜索。有人说用这样的：

A few have said to me to use the explode and substr to split the filename up and then i guess search through the array. Someone said to use this:

$array = explode(' ', $filename); 
$firstTwoLetters = string substr ($array[1], 0, 2);

但我得到的变量名的错误没有定义。

But i get the error of variable filename not defined.

不幸的是我不知道。我通过论坛搜索论坛和发布的帖子后，我想出了这个迄今为止后：

Unfortunately i have no clue. I have search through forums after forums and postings after postings, i have come up with this so far:

if(JFile::exists($searchpath .DS. '.doc')){
    JFile::move($searchpath .DS. '.doc', JPATH_BASE .DS. 'upload' .DS. 'Nathan' .DS. '.doc'); }

我的目录结构是这样的：

My directory structure looks like this:

root/wan/upload - Where files/images/docs are stored. Inside upload folder i have:
>2014-04-08 NS6565.doc
>2012-01-03 JB8932.doc
>2013-02-01 GA5434.doc
>etc
root/wan/administrator/components/com_upload - where my code is stored

问题是我有几百万的这些文件，并在上面我给的例子的开始日期将每一个变化。

Problem is i have millions of these files, and the date at the start of the example i gave above will change for each.

我试图把它们放入一个数组但是从那里不知道如何再拆/调用合适的人摆在正确的文件夹：

I have tried putting them into an array but not sure from there how to then split/call the right one to put in the right folder:

尝试 - 阵列

$dir    = JPATH_BASE . DS . "upload";
$basename = basename($dir);
$array = scandir($dir);
$filename = basename($dir[0]);
print_r($array);
print_r($basename);

任何帮助很多AP preciated。或者，如果你可以点我的例子/文档将是伟大的。

Any help is much appreciated. Or if you can point me to examples/documentation that'll be great.

感谢

推荐答案

假设DS是DIRECTORY_SEPARATOR

Assuming DS is DIRECTORY_SEPARATOR

$dir    = JPATH_BASE . DS . "upload";
$folders = array('NS'=>'/path/to/Nathan/Saunders/Folder','JB'=>'/path/to/Joe/Bailey/folder');
$files  = scandir($dir);
foreach($files AS $file){
    if(!is_file($dir.DS.$file)){ continue; }
    $array = explode(' ', $file);
    if(count($array)<2){ continue; }
    $firstTwoLetters = substr($array[1], 0, 2);
    if(!empty($folders[$firstTwoLetters])){
        rename($dir.DS.$file,$folders[$firstTwoLetters].DS.$file);
    }
}
