PHP:不带文件扩展名的文件名-最佳方法?

问题描述：

我正在尝试将文件名从不带扩展名的目录中拉出.

I am trying to pull the filename out of a directory without the extension.

我正在遵循以下步骤进行操作:

I am kludging my way through with the following:

foreach ($allowed_files as $filename) { 
  $link_filename = substr(basename($filename), 4, strrpos(basename($filename), '.'));
  $src_filename = substr($link_filename, 0, strrpos($link_filename) - 4);
  echo $src_filename;
}

...但是，如果扩展字符串长度超过3，则无法使用. 我在PHP文档中环顾四周，无济于事.

...But that can't work if the extension string length is more than 3. I looked around in the PHP docs to no avail.

答

PHP有一个方便的

PHP has a handy pathinfo() function that does the legwork for you here:

foreach ($allowed_files as $filename) {
  echo pathinfo($filename, PATHINFO_FILENAME);
}

示例:

$files = array(
  'somefile.txt',
  'anotherfile.pdf',
  '/with/path/hello.properties',
);

foreach ($files as $file) {
  $name = pathinfo($file, PATHINFO_FILENAME);
  echo "$file => $name\n";
}

输出:

somefile.txt => somefile
anotherfile.pdf => anotherfile
/with/path/hello.properties => hello
