basename()

(PHP 4, PHP 5, PHP 7)

返回路径中的文件名部分

说明

给出一个包含有指向一个文件的全路径的字符串，本函数返回基本的文件名。

参数

一个路径。

在 Windows 中，斜线（/）和反斜线（）都可以用作目录分隔符。在其它环境下是斜线（/）。

如果文件名是以$suffix结束的，那这一部分也会被去掉。

返回值

Returns the base name of the given$path.返回$path的基本的文件名。

范例

Example #1basename()例子

以上例程会输出：

1) sudoers
2) passwd
3) etc
4) .
5) 

注释

basename()operates naively on the input string, and is not aware of the actual filesystem, or path components such as "..".Note:

basename()is locale aware, so for it to see the correct basename with multibyte character paths, the matching locale must be set using thesetlocale()function.

• pathinfo() 返回文件路径的信息

Support of the $suffix parameter has changed between PHP4 and PHP5:
in PHP4, $suffix is removed first, and then the core basename is applied.
conversely, in PHP5, $suffix is removed AFTER applying core basename.
Example:

Result in PHP4: file
Result in PHP5: Texture)

It's a shame, that for a 20 years of development we don't have mb_basename() yet!
// works both in windows and unix
function mb_basename($path) {
  if (preg_match('@^.*[\\\\/]([^\\\\/]+)$@s', $path, $matches)) {
    return $matches[1];
  } else if (preg_match('@^([^\\\\/]+)$@s', $path, $matches)) {
    return $matches[1];
  }
  return '';
}

There is only one variant that works in my case for my Russian UTF-8 letters:
