PathInfo () different results for multi-byte character processing in different versions of PHP

The Phpinfo () function is unable to process multibyte characters in the lower version of PHP while processing the path, the difference between php5.3 and php5.6 is tested here

<?php// your code goes hereecho phpversion();print_r(pathinfo("/resources/img/stock/wxb001/美景.png")); 输出：5.6.4-2Array(    [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 hereecho phpversion();print_r(pathinfo("/resources/img/stock/wxb001/美景.png")); 输出：5.3.3Array(    [dirname] => /var/www/www.shima.jp.net/resources/img/stock/wxb001    [basename] => .png    [extension] => png    [filename] => )Also, basename () in php5.3 filters out multibyte characters echo basename ('/resources/img/stock/wxb001/view. png ')//output:. png

The following method can be used in the lower version to implement multibyte character processing

<?php// your code goes here$file = '/resources/img/stock/wxb001/view. png ';$file_dir = dirname($file );$file_basename = substr(strrchr($file, DIRECTORY_SEPARATOR), 1);$file_name = substr($file_basename, 0, strrpos($file_basename, "."));$file_extension = end(explode(".", $file_basename));echo $file_dir; // /resources/img/stock/wxb001echo $file_basename;  // 美景.pngecho $file_name; // 美景echo $file_extension; // png
