SPLFileInfo:获取不带扩展名的文件名 [英] SPLFileInfo: get filename without extension

问题描述

我正在访问SPLFileInfo对象中的许多文件.我看到了一种获取路径，文件名甚至文件扩展名的方法.有没有办法获取不带扩展名的文件名?这是我一直在使用的代码，但我希望得到一些更优雅的东西.是否有开箱即用的解决方案?

I'm accessing a number of files in the SPLFileInfo object. I see a way to get the path, filename, and even extension of the file. Is there a way to get the filename without extension? Here's the code I've been working with but I'm hoping to get something more elegant. Is there an out of the box solution?

$file = new SplFileInfo("path/to/file.txt.zip"); 

echo 'basename: '.$file->getBasename();  
echo PHP_EOL;
echo 'filename: '.$file->getFilename();
echo PHP_EOL;    
echo 'extension: '.$file->getExtension();
echo PHP_EOL;    
echo 'basename w/o extension: '.$file->getBasename('.'.$file->getExtension());

>>OUTPUT
>>basename: file.txt.zip
>>filename: file.txt.zip
>>extension: zip
>>basename w/o extension: file.txt

推荐答案

我来晚了，所有功劳都应该归功于@salathe，这是第一位帮助OP的人，但这是

I'm late and all the credits should go to @salathe being the first helping the OP, but here's the link to PHP manual for basename function. Basically, you get the extension, then prepend a dot . and finally use the basename function to get the name, like this:

$file->getBasename('.' . $file->getExtension())

为了快速阅读，这是PHP手册页的示例:

For fast reading, here's the PHP manual page's example:

$info = new SplFileInfo('file.txt');
var_dump($info->getBasename());

$info = new SplFileInfo('/path/to/file.txt');
var_dump($info->getBasename());

$info = new SplFileInfo('/path/to/file.txt');
var_dump($info->getBasename('.txt'));

输出:

string(8) "file.txt"
string(8) "file.txt"
string(4) "file"
