php实现复制移动文件的方法,
php实现复制移动文件的方法,
本文实例讲述了php实现复制移动文件的方法。分享给大家供大家参考。具体如下:
仿写elFinder的,抽出关键的成员方法做的一个简单示例
实现功能是:
实现多文件复制或移动操作
注:为了方便测试,对一些判断做了简单处理。并且会在程序文件所在目录下
新生成一个test文件夹作为目的文件夹。如果实际使用需要修改。
copy.php文件如下:
<?php /** * 复制/移动操作简单示例 : >PHP5 * */ /** * 判断文件是否存在 * */ function _isFind($filename) { return @file_exists($filename); } /** * 判断文件夹是否存在? 简单处理: 仅对根目录进行判断 * */ function _isFindDir($dir) { $ls = scandir(dirname(__FILE__)); foreach ($ls as $val) { if ($val == $dir) return TRUE; } return FALSE; } /** * 复制或移动 * * @param array 源文件夹数组: 简单处理:采用文件名作为元素值 * @param string 目的文件夹 * @param string 操作数: move - 移动 ; copy - 复制 * @return bool */ function _copy_move($src = array(), $dst = '', $op = 'move') { if ( ! is_array($src)) { $src = array($src); } //判断源文件是否存在? foreach ($src as $val) { if ( _isFind($val) === FALSE) { return _log('Src file not find', $val); } } //判断目的文件夹是否存在? 如果不存在就生成 //简单处理: 实际应用需要修改 if (_isFindDir($dst) === FALSE) { @mkdir($dst); } //执行移动或复制操作 foreach ($src as $val) { $_dst = $dst.'/'.basename($val); //判断目的文件是否存在? 存在不允许进行操作 if (_isFind($_dst) === TRUE) { return _log('Dst file is exists', $dst); } else if (strpos($dst, $val) === 0) { return _log('Unable to copy/move into itself'); } if (strtolower($op) === 'move') { if ( ! rename($val, $_dst)) { return _log('Unable to move files', $val); } } else if (strtolower($op) === 'copy') { if ( ! _copy($val, $_dst)) { return _log('Unable to copy files', $val); } } } return 'Success!'; } /** * 复制操作 * */ function _copy($src, $dst) { if ( ! is_dir($src)) { if ( ! copy($src, $dst)) { return _log('Unable to copy files', $src); } } else { mkdir($dst); $ls = scandir($src); for ($i = 0; $i < count($ls); $i++) { if ($ls[$i] == '.' OR $ls[$i] == '..') continue; $_src = $src.'/'.$ls[$i]; $_dst = $dst.'/'.$ls[$i]; if ( is_dir($_src)) { if ( ! _copy($_src, $_dst)) { return _log('Unable to copy files', $_src); } } else { if ( ! copy($_src, $_dst)) { return _log('Unable to copy files', $_src); } } } } return TRUE; } /** * 日志记录 * */ function _log($msg, $arg = '') { if ($arg != '') { $msg = "date[".date('Y-m-d H:i:s')."]\tmsg[".$msg."]\targ[".$arg."]\n"; } else { $msg = "date[".date('Y-m-d H:i:s')."]\tmsg[".$msg."]\n"; } echo $msg; return @file_put_contents('copy.log', $msg, FILE_APPEND); } /** * 示例 * 1. 需要修改$src的数组参数 ; 2. 可以修改_copy_move的第三个参数以分别测试move/copy操作 * */ $src = array('img', 'min', 'phpinfo.php'); $dst = 'test'; var_dump(_copy_move($src, $dst, 'copy')); /*end of php*/

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
