PHP上傳的簡單案例：
Html檔案：
<html><form action="index.php" name="form" method="post" enctype="multipart/form-data"> <input type="file" name="file" /> <input type="submit" name="submit" value="上傳" /></form></html>
PHP檔案：
<?php$file = $_FILES[‘file‘];//得到傳輸的資料//得到檔案名稱$name = $file[‘name‘];$type = strtolower(substr($name,strrpos($name,‘.‘)+1)); //得到檔案類型，並且都轉化成小寫$allow_type = array(‘jpg‘,‘jpeg‘,‘gif‘,‘png‘); //定義允許上傳的類型//判斷檔案類型是否被允許上傳if(!in_array($type, $allow_type)){ //如果不被允許，則直接停止程式運行 return ;}//判斷是否是通過HTTP POST上傳的if(!is_uploaded_file($file[‘tmp_name‘])){ //如果不是通過HTTP POST上傳的 return ;}$upload_path = "./img/"; //上傳檔案的存放路徑//開始移動檔案到相應的檔案夾if(move_uploaded_file($file[‘tmp_name‘],$upload_path.$file[‘name‘])){ echo "Successfully!";}else{ echo "Failed!";}?>
使用thinkphp上傳類上傳的簡單案例：
// 上傳配置資訊 protected $upconfig = array( ‘maxSize‘ => 3145728, // 3M ‘exts‘ => array(‘jpg‘, ‘gif‘, ‘png‘, ‘jpeg‘), ‘rootPath‘ => ‘./Public/Uploads/info/‘, ‘savePath‘ => ‘‘, // => 上傳子目錄需要每個函數自己去設定 ‘saveName‘ => array(‘uniqid‘,‘‘), ‘autoSub‘ => false, // 關閉子目錄儲存 ‘subName‘ => array(‘date‘,‘Ymd‘), ); protected function upload($file) { $res[‘result‘] = 1; $res[‘imgurl‘] = ‘‘; $res[‘msg‘] = ‘‘; do { $ret = true;
//判斷路徑是否存在 $fullPath = $this->upconfig[‘rootPath‘] . $this->upconfig[‘savePath‘]; if(!file_exists($fullPath)){
//如果不存在，建立檔案夾 $ret = mkdir($fullPath, 0777, true); } if(!$ret) { // 上傳錯誤提示錯誤資訊 $res[‘result‘] = 0; $res[‘msg‘] = "建立儲存圖片的路徑失敗！"; break; } // 執行個體化上傳類 $upload = new \Think\Upload($this->upconfig); // 上傳單個檔案 $info = $upload->uploadOne($file); if(!$info) { // 上傳錯誤提示錯誤資訊 $res[‘result‘] = 0; $res[‘msg‘] = $upload->getError(); } else { // 上傳成功 擷取上傳檔案資訊 $imgurl = $this->upconfig[‘rootPath‘] . $info[‘savepath‘].$info[‘savename‘]; $imgurl = str_replace(‘./‘, ‘/‘, $imgurl); $res[‘result‘] = 1; $res[‘imgurl‘] = $imgurl; } } while(0); return $res; } // 儲存上傳的檔案 $res = $this->upload($_FILES[‘attorney‘]);
通過司機端App上傳圖片，介面：
註：IOS或者安卓端：通過把圖片進行base64編碼得到字串，傳給介面
介面端：把接收的字串進行base64解碼，再通過file_put_contents函數，上傳到指定的位置
