/* 自定义的删除函数,可以删除文件和递归删除文件夹 */ function my_del($path) { if(is_dir($path)) { $file_list= scandir($path); foreach ($file_list as $file) { if( $file!='.' && $file!='..') { my_del($path.'/'.$file); } } @rmdir($path); //这种方法不用判断文件夹是否为空, //因为不管开始时文件夹是否为空,到达这里的时候,都是空的 } else { @unlink($path); //这两个地方最好还是要用@屏蔽一下warning错误,看着闹心 } } $path='d:/技术文档 - 副本'; //要删除的文件夹 //如果php文件不是ANSI,而是UTF-8模式, //而且要删除的文件夹中包含汉字字符的话,调用函数前需要转码 //$path=iconv( 'utf-8', 'gb2312',$path ); my_del($path);

/* Customized deletion function, which can delete files and recursively delete folders */ function my_del($path) { if(is_dir($path)) { $file_list= scandir($path); foreach ($file_list as $file) { if( $file!='.' && $file!='..') { my_del($path.'/'.$file); } } @rmdir($path); //This method does not need to determine whether the folder is empty, //Because no matter whether the folder is empty at the beginning, it will be empty when you get here } else { @unlink($path); //It’s best to use @ to block warning errors in these two places, which will look annoying } } $path='d:/Technical Documentation - Copy'; //Folder to be deleted //If the php file is not ANSI, but UTF-8 mode, //If the folder to be deleted contains Chinese characters, it needs to be transcoded before calling the function //$path=iconv( 'utf-8', 'gb2312',$path ); my_del($path);
