<?php

// your code goes here

echo phpversion();

print_r(pathinfo("/resources/img/stock/wxb001/美景.png"));

输出：

5.6.4-2

Array

(

    [dirname] => /resources/img/stock/wxb001

    [basename] => 美景.png

    [extension] => png

    [filename] => 美景

)

但是在php5.3.3版本中

<?php

// your code goes here

echo phpversion();

print_r(pathinfo("/resources/img/stock/wxb001/美景.png"));

输出：

5.3.3

Array

(

    [dirname] => /var/www/www.shima.jp.net/resources/img/stock/wxb001

    [basename] => .png

    [extension] => png

    [filename] =>

)

// 同时，在php5.3中basename()也会过滤掉多字节字符

echo basename(‘/resources/img/stock/wxb001/美景.png‘)

// 输出：.png
