例如，如果我有一个路径(由torrent_info_gen生成)-

For example if i have a path (generated by my torrent_info_gen)-

Driver Genius Professional Edition 10.0.0.526/Driver Genius Professional Edition 10.0.0.526.exe

我应该如何在路径中获取文件的扩展名！ 我还希望以这种方式以不同的方式显示路径和文件名:

How should i get the extension of the file in the path! I also want to have the path and filename to be shown differently in this way:

路径:(文件的路径)

文件名:(文件名)

扩展名:(文件的扩展名)

有人可以帮助我！ 请!!!!!

Can someone help me! Please!!!!!

提前谢谢！

推荐答案

这是怎么回事:

    $str = "Driver Genius Professional Edition 10.0.0.526/Driver Genius Professional Edition 10.0.0.526.exe";

    $info  = pathinfo($str);

    var_dump($info['dirname']);
    var_dump($info['filename']);
    var_dump($info['extension']);

赠予:

string 'Driver Genius Professional Edition 10.0.0.526' (length=45)
string 'Driver Genius Professional Edition 10.0.0.526' (length=45)
string 'exe' (length=3)
