PHP 批量移动文件改名

Posted 2020-06-18 studyphp

public function changeCoverName(){
    //$type = ‘考研‘;
    //$coverPath = ‘./Public/course_cover/kaoyan/‘;
    $type = ‘四六级‘;
    $coverPath = ‘./Public/course_cover/four-six/‘;//源目录


    $targetPath = ‘./Upload/img/course_img/cover/‘.md5($type).‘/‘;//目标目录

    //移动文件
    $this->recurseCopy($coverPath,$targetPath);

    //移动后改名文件
    $this->changeName($targetPath);

}

移动文件函数

//目录文件移动,简洁 高效
public function recurseCopy($src,$dst) {  // 原目录，复制到的目录
    $dir = opendir($src);
    @mkdir($dst);
    while(false !== ( $file = readdir($dir)) ) {
        if (( $file != ‘.‘ ) && ( $file != ‘..‘ )) {
            if ( is_dir($src . ‘/‘ . $file) ) {
                $this->recurseCopy($src . ‘/‘ . $file,$dst . ‘/‘ . $file);
            }
            else {
                copy($src . ‘/‘ . $file,$dst . ‘/‘ . $file);
            }
        }
    }
    closedir($dir);
}

//改名函数
    public function changeName($targetPath){
        $d = dir($targetPath);
        while (false !== ($entry = $d->read())) {
            $newStr = explode(‘.‘,$entry);
            $newStr[0] = iconv(‘gbk‘,‘utf-8‘,$newStr[0]);
            $newName = md5($newStr[0]);
//            echo $newStr[0].‘---‘.$newName.‘<br/>‘;
            rename($targetPath.$entry, $targetPath.$newName.".".$newStr[1]);
        }
        $d->close();
    }
