簡(jiǎn)單講解下PHP服務(wù)端接受客戶端上傳的文件
客戶端上傳文件到服務(wù)器,帶參數(shù),并且進(jìn)行用戶驗(yàn)證,方法很簡(jiǎn)單

直接貼代碼

<?php

    //強(qiáng)制顯示錯(cuò)誤
    error_reporting(E_ALL);
    // error_reporting = E_ALL & ~E_NOTICE
    ini_set('display_errors', '1');

    $UserId = str_replace("'", "", $_REQUEST["UserId"]);//接收用戶ID
    $Token = str_replace("'", "", $_REQUEST["Token"]);//接收Token
    $sql = "SELECT * FROM `im_user` WHERE `UserId` = '$UserId'";
    $request = mysql_fetch_assoc(mysql_query($sql));
    //進(jìn)行驗(yàn)證,如果驗(yàn)證通過(guò),處理接收文件
    if (md5($UserId.$request["UserToken"]."qwertyuiop") == $Token) 
    {    
        //判斷是否有文件上傳
        if (isset($_FILES['file'])) {
            //定義文件
            $name = time().rand(10000000,99999999);
            $target_path  = "./uploadfile/";//接收文件目錄
            // echo $target_path.$name.$_FILES['file']['type']; 
            // $target_path = $target_path.basename($_FILES['file']['name']);
            $target_path = $target_path.basename($name.".FT");
            //將文件從臨時(shí)目錄拷貝到指定目錄
            if(move_uploaded_file($_FILES['file']['tmp_name'], $target_path)) {    
            //上傳成功,可進(jìn)行進(jìn)一步操作,將路徑寫(xiě)入數(shù)據(jù)庫(kù)等.
                echo "The file ".basename( $_FILES['file']['name']). " has been uploaded";
            }  else{    
                 echo "There was an error uploading the file, please try again!" . $_FILES['file']['error'];
            }
            exit;
        }else
        {
            echo "沒(méi)有文件";
        }
    }else
    {
        echo "認(rèn)證不通過(guò)!";
    }
