& Python模块学习：glob 文件路径查找
glob模块是最简单的模块之一，内容非常少。用它可以查找符合特定规则的文件路径名。跟使用windows下的文件搜索差不多。查找文件只用到三个匹配符：”*”, “?”, “[]”。”*”匹配0个或多个字符；”?”匹配单个字符；”[]”匹配指定范围内的字符，如：[0-9]匹配数字。
返回所有匹配的文件路径列表。它只有一个参数pathname，定义了文件路径匹配规则，这里可以是绝对路径，也可以是相对路径。下面是使用glob.glob的例子：
import glob
#获取指定目录下的所有图片
print glob.glob(r"E:/Picture/*/*.jpg")
#获取上级目录的所有.py文件
print glob.glob(r'../*.py') #相对路径
import glob&#获取指定目录下的所有图片print glob.glob(r"E:/Picture/*/*.jpg")&#获取上级目录的所有.py文件print glob.glob(r'../*.py') #相对路径
glob.iglob
获取一个可编历对象，使用它可以逐个获取匹配的文件路径名。与glob.glob()的区别是：glob.glob同时获取所有的匹配路径，而glob.iglob一次只获取一个匹配路径。这有点类似于.NET中操作数据库用到的DataSet与DataReader。下面是一个简单的例子：
import glob
#父目录中的.py文件
f = glob.iglob(r'../*.py')
print f #&generator object iglob at 0x00B9FF80&
for py in f:
import glob&#父目录中的.py文件f = glob.iglob(r'../*.py')&print f #&generator object iglob at 0x00B9FF80&&for py in f:&&&&print py
It’s so easy, is’t it?

& 2017 伯乐在线PHP 列出指定路径中的文件和目录
在线手册：&
scandir & 列出指定路径中的文件和目录
array scandir
( string $directory
[, int $sorting_order
[, resource $context
要被浏览的目录
sorting_order
默认的排序顺序是按字母升序排列。如果使用了可选参数
sorting_order（设为
1），则排序顺序是按字母降序排列。
context 参数的说明见手册中的
成功则返回包含有文件名的 ，如果失败则返回
FALSE。如果 directory
不是个目录，则返回布尔值 FALSE 并生成一条
E_WARNING 级的错误。
Example #1 一个简单的
scandir() 例子
&?php$dir&&&&=&'/tmp';$files1&=&scandir($dir);$files2&=&scandir($dir,&1);print_r($files1);print_r($files2);?&
以上例程的输出类似于：
[2] =& bar.php
[3] =& foo.txt
[4] =& somedir
[0] =& somedir
[1] =& foo.txt
[2] =& bar.php
Example #2
scandir() 在 PHP 4 中的实现
&?php$dir&=&"/tmp";$dh&&=&opendir($dir);while&(false&!==&($filename&=&readdir($dh)))&{&&&&$files[]&=&$filename;}sort($files);print_r($files);rsort($files);print_r($files);?&
以上例程的输出类似于：
[2] =& bar.php
[3] =& foo.txt
[4] =& somedir
[0] =& somedir
[1] =& foo.txt
[2] =& bar.php
Tip如已启用，在此函数中， URL 可作为文件名。关于如何指定文件名详见
wapper 的不同功能请参见 ，注意其用法及其可提供的预定义变量。
- 打开目录句柄
- 从目录句柄中读取条目
- 寻找与模式匹配的文件路径
- 判断给定文件名是否是一个目录
- 对数组排序

If you would like to use scandir on the root directory of your server, you would imagine the command to be either scandir(&&) or scandir(&/&), but neither work.
However, scandir(&.&) works perfectly.
Use scandir(&/&) and scandir(&..&) to poke around the Linuxy areas of your webhost.
At least, these are the observations I've made with my own webhost when it comes to root directory scandir.
This method would leave the file system vulnerable using ../ for the ?dir= A person could navigate any readable file system simply by adding ../ enough times to get back to the root of the drive.
On a proper secure system this might not matter, however for less secure file systems where the web user(apache user) can at least read most files, or on multi-user web servers this could lead to potential security risks.
Adding a check to see if ../ is in the
$_GET[&dir&] is one way to prevent this.

Note that target directory has to be 0755 (rwxr-xr-x) for it to be &readable& instead of the &read& permits 0744 (rwxr--r--).
This happens in &is_readable& function too.
If&you&wish&to&sort&by&folders&first&then&files,&you&could&use&something&like&this:&?phpfunction&scandirSorted($path)&{&&&&$sortedData&=&array();&&&&foreach(scandir($path)&as&$file)&{&&&&&&&&if(is_file($path&.&$file))&{&&&&&&&&&&&&array_push($sortedData,&$file);&&&&&&&&}&else&{&&&&&&&&&&&&array_unshift($sortedData,&$file);&&&&&&&&}&&&&}&&&&return&$sortedData;}?&NB.:&This&approach&*might*&be&suboptimal&for&high&performance&situations.-&Gerard

Note that scandir() will enforce alphanumerical sorting on the array it returns. If you wish to reduce CPU overhead by avoiding the sorting, or if you wish to obtain &natural filesystem order& - that is, the order in which the files are found while traversing the filesystem (usually the order in which they were written to the disk) - you need to go back to the PHP4 equivalent of opendir() + readdir().
We&can&do&a&select&dir&in&a&array
&?php
function&mi_dir_list($a_path=".",&$a_mask="*")
{&
&&&&$dir&=&@&dir("$a_path");
&&&&//List&files&in&images&directory
&&&&while&(($file&=&$dir-&read())&!==&false)

Scandir does not work properly with non-english caracters (like french accents for example : éà?è...) in the files name.
As PHP does not support unicode operations until PHP 6, this is not a bug.

Just noticed a minor difference between scandir and readdir.
When opening a directory and using readdir(), each file appears to be accessed in the process.
This resets the &Last Accessed& time that you would get with fileatime().
With scandir(), the list is created and none of the files are accessed.
Therefore the access times remain unchanged.
I encountered this while writing a script to scan a directory and delete any file that hadn't been accessed in x time.
Kind of defeated the purpose when the directory listing accessed every file...

Since&scandir()&returns&and&array,&here&is&a&more&concise&method&of&dealing&with&the&'.'&and&'..'&problem&when&listing&directories:
&?php
$target&=&'/';
$weeds&=&array('.',&'..');
$directories&=&array_diff(scandir($target),&$weeds);
&&&&
foreach($directories&as&$value)
{
&&&if(is_dir($target.$value))
&&&{
&&&&&&echo&$value.'&br&/&';
&&&}
}

Bear in mind that sorting is *always* performed when scandir() is called. String sorting takes O(|s|n log n) runtime, and this adds to the burden of the server's memory and processing power.
Therefore, whenever the alphabetical order of the directory content is unimportant, especially if sorting is to be performed by another order, or the natural order of the files on the filesystem is to be utilized, the use of opendir(), readdir() and closedir() combined is always preferred to scandir().
