本文实例讲述了PHP多文件上传类,分享给大家供大家参考。具体如下:
<?php class Test_Upload{ protected $_uploaded = array(); protected $_destination; protected $_max = 1024000; protected $_messages = array(); protected $_permited = array( \'image/gif\', \'image/jpeg\', \'image/pjpeg\', \'image/png\' ); protected $_renamed = false; /** * * @param mix $path * */ public function __construct($path){ if (!is_dir($path) || !is_writable($path)){ throw new Exception(\"文件名不可写,或者不是目录!\"); } $this->_destination = $path; $this->_uploaded = $_FILES; } /** * 移动文件 * */ public function move(){ $filed = current($this->_uploaded); $isOk = $this->checkError($filed[\'name\'], $filed[\'error\']); //debug ok if ($isOk){ $sizeOk = $this->checkSize($filed[\'name\'], $filed[\'size\']); $typeOk = $this->checkType($filed[\'name\'], $filed[\'type\']); if ($sizeOk && $typeOk){ $success = move_uploaded_file($filed[\'tmp_name\'], $this->_destination.$filed[\'name\']); if ($success){ $this->_messages[] = $filed[\'name\'].\"文件上传成功\"; }else { $this->_messages[] = $filed[\'name\'].\"文件上传失败\"; } } } } /** * 查询messages数组内容 * */ public function getMessages(){ return $this->_messages; } /** * 检测上传的文件大小 * @param mix $string * @param int $size */ public function checkSize($filename, $size){ if ($size == 0){ return false; }else if ($size > $this->_max){ $this->_messages[] = \"文件超出上传限制大小\".$this->getMaxsize(); return false; }else { return true; } } /** * 检测上传文件的类型 * @param mix $filename * @param mix $type */ protected function checkType($filename, $type){ if (!in_array($type, $this->_permited)){ $this->_messages[] = \"该文件类型是不被允许的上传类型\"; return false; }else { return true; } } /** * 获取文件大小 * */ public function getMaxsize(){ return number_format($this->_max / 1024, 1).\'KB\'; } /** * 检测上传错误 * @param mix $filename * @param int $error * */ public function checkError($filename, $error){ switch ($error){ case 0 : return true; case 1 : case 2 : $this->_messages[] = \"文件过大!\"; return true; case 3 : $this->_messages[] = \"错误上传文件!\";return false; case 4 : $this->_messages[] = \"没有选择文件!\"; return false; default : $this->_messages[] = \"系统错误!\"; return false; } } } ?>
希望本文所述对大家的php程序设计有所帮助。
