PHP：如何在文件上传中删除不必要的文件名点？ [英] PHP: How to remove unnecessary dots in filename on file upload?

问题描述

我有一个脚本来上传PHP文件。
我已经做了一些清理工作来删除难看的字符。

我也想删除文件名中的点，除了最后一个，表示文件扩展名。

任何人都有一个想法，我可以做到这一点。

例如，得到

  $ filename =water.fall_blue.sky.jpg; 
 $ filename2 =water.fall_blue.sky.jpeg; 
  

在这两种情况下都会返回这个结果..？

  water.fall_blue.sky 
  

解决方案

使用 pathinfo（） 提取文件名（自PHP 5.2起，filename数组元素可用）; str_replace（）所有的点出来;并重新粘贴文件扩展名。

I have a script to upload files with PHP. I already do some cleaning to remove ugly characters.

I would also like to to remove dots in the filename, EXCEPT for the last one, which indicates the file extension.

Anyone has an idea how I could do that.?

For example, how would you get

$filename = "water.fall_blue.sky.jpg";
$filename2 = "water.fall_blue.sky.jpeg";

to return this in both cases..?

water.fall_blue.sky

解决方案

Use pathinfo() to extract the file name (the "filename" array element is available since PHP 5.2); str_replace() all the dots out of it; and re-glue the file extension.
