這篇文章主要為大家分享了一個(gè)適用于初學(xué)者的簡(jiǎn)易PHP文件上傳類(lèi),具有一定的參考價(jià)值,感興趣的小伙伴們可以參考一下
本文實(shí)例講述了PHP多文件上傳類(lèi),分享給大家供大家參考。具體如下:
- <?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("文件名不可寫(xiě),或者不是目錄!");
- }
- $this->_destination = $path;
- $this->_uploaded = $_FILES;
- }
- /**
- * 移動(dòng)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']."文件上傳成功";
- }else {
- $this->_messages[] = $filed['name']."文件上傳失敗";
- }
- }
- }
- }
- /**
- * 查詢(xún)messages數(shù)組內(nèi)容
- *
- */
- public function getMessages(){
- return $this->_messages;
- }
- /**
- * 檢測(cè)上傳的文件大小
- * @param mix $string
- * @param int $size
- */
- public function checkSize($filename, $size){
- if ($size == 0){
- return false;
- }else if ($size > $this->_max){
- $this->_messages[] = "文件超出上傳限制大小".$this->getMaxsize();
- return false;
- }else {
- return true;
- }
- }
- /**
- * 檢測(cè)上傳文件的類(lèi)型
- * @param mix $filename
- * @param mix $type
- */
- protected function checkType($filename, $type){
- if (!in_array($type, $this->_permited)){
- $this->_messages[] = "該文件類(lèi)型是不被允許的上傳類(lèi)型";
- return false;
- }else {
- return true;
- }
- }
- /**
- * 獲取文件大小
- *
- */
- public function getMaxsize(){
- return number_format($this->_max / 1024, 1).'KB';
- }
- /**
- * 檢測(cè)上傳錯(cuò)誤
- * @param mix $filename
- * @param int $error
- *
- */
- public function checkError($filename, $error){
- switch ($error){
- case 0 : return true;
- case 1 :
- case 2 : $this->_messages[] = "文件過(guò)大!"; return true;
- case 3 : $this->_messages[] = "錯(cuò)誤上傳文件!";return false;
- case 4 : $this->_messages[] = "沒(méi)有選擇文件!"; return false;
- default : $this->_messages[] = "系統(tǒng)錯(cuò)誤!"; return false;
- }
- }
- }
- ?>
希望本文所述對(duì)大家的php程序設(shè)計(jì)有所幫助。
