During the project development process, I encountered automatic updates on the app side. I consulted relevant information and sorted out the method for the Appcan client to automatically update the PHP version number. The specific code is explained below.

Server files: update.php, version.php, version.xml

update.php content:

PHP

<&#63;php
define('CIN', true);
$oldver = $_REQUEST['ver'];//客户端传过来的版本号
$platform = $_REQUEST['platform'];//客户端的平台
$info = simplexml_load_file('version.xml');
$iphone_filename=$info->news['iphone_filename']; //iphone下载文件
$android_filename=$info->news['android_filename']; //androiad下载文件
$version=$info->news['version']; //版本号
if ($version>$oldver)
{
  switch ($platform)
  {
    case "0"://iphone
      echo "<&#63;xml version=\"1.0\" encoding=\"utf-8\"&#63;>";
      echo "<results>";
      echo "<updateFileName>i2ty</updateFileName>";//客户端名字
      echo "<updateFileUrl>itunesURL</updateFileUrl>";//返回给客户端的下载地址
      echo "<fileSize>0</fileSize>";//文件大小
      echo "<version>".$version."</version>";//版本信息
      echo "</results>";
      break;
    case "1"://android
      echo "<&#63;xml version=\"1.0\" encoding=\"utf-8\"&#63;>";
      echo "<results>";
      echo "<updateFileName>i2ty</updateFileName>";//客户端名字
      echo "<updateFileUrl>http://i2ty.com/app/".$android_filename."</updateFileUrl>";//返回给客户端的下载地址
      echo "<fileSize>0</fileSize>";//文件大小
      echo "<version>".$version."</version>";//版本信息
      echo "</results>";
      break;
  }
}
&#63;>

version.php content:

PHP

<&#63;php
define('CIN', true);
$result['vtitle']="更新";
$result['vcontent']="新版本有更新喔!~新增功能修复各种错误";
print_r(json_encode($result));
&#63;>
version.xml 内容:
PHP
<&#63;xml version="1.0" encoding="utf-8" &#63;>
<root desc="Login">
 <news version="00.00.0001" iphone_filename="i2ty.ipa"  android_filename="i2ty.apk" />
</root>
index.html 客户端:
PHP
window.uexOnload = function(type){   
    if (!type) {
      update();
    }
var flag_sdcard = 1;
var updateurl = '';//下载新apk文件地址
var filepath2 = "/sdcard/";//保存到sd卡
var fileName = '';//新版本文件名
var platform = '';//平台版本
function update()
{  
    //安卓版 ,显示下载进度 (step:7)
    uexDownloaderMgr.onStatus = function(opId, fileSize, percent, status) {
        if (status == 0) {
            // 下载中...
            Log('download percent ' + percent + '%');
            uexWindow.toast('1', '5', '正在下载'+localStorage.app_title+'新版,请稍后。进度:' + percent + '%', '');
        } else if (status == 1) {// 下载完成.
            uexWindow.closeToast();
            uexDownloaderMgr.closeDownloader('14');//关闭下载对象
            uexWidget.installApp(filepath2+fileName);// 安装下载apk文件
        } else {
            uexWindow.toast('1', '5', '下载出错,请关闭'+localStorage.app_title+'再次运行.', '');
        }
    };
    //安卓版 ,创建下载对象回调函数(step:6)
    uexDownloaderMgr.cbCreateDownloader = function(opId, dataType, data) {
        Log('uexDownloaderMgr.cbCreateDownloader data='+data);
        if (data == 0) {
            //updateurl是通过调用cbCheckUpdate回调后,放入全局变量的
            uexDownloaderMgr.download('14', updateurl, filepath2+fileName, '0');//开始下载apk文件
        } else if (data == 1) { 
            ;
        } else {
            ;
        }
    };
    //提示更新模态框按钮事件回调函数,判断用户选择更新还是取消 (step:5)
    uexWindow.cbConfirm = function(opId, dataType, data) {
        Log('uexWindow.cbConfirm ');
        //调用对话框提示函数
        if (data == 0) {
            //用户点击稍后按钮,不进行更新
        } else {
            //用户点击确定按钮,进行更新
            if (platform == 0) {
                //苹果版更新,通过浏览器加载appstore路径
                uexWidget.loadApp(updateurl,'','');
                //uexWidget.loadApp("", "", updateurl);//旧方法 已经不可以使用了。
            } else if (platform == 1) {
                //安卓版更新,通过创建下载对象进行下载                
                uexDownloaderMgr.createDownloader("14");
            } else {
                ;
            }
        }
    };
    //调用检查更新回调函数,请求成功后,弹出模态框让用户选择是否现在更新(step:4)
    uexWidget.cbCheckUpdate = function(opCode, dataType, jsonData) {        
        Log('jsonData='+jsonData);
        var obj = eval('(' + jsonData + ')');
        if (obj.result == 0) {
            // tips = "更新地址是:" + obj.url + "<br>文件名:" + obj.name + "<br>文件大小:" +
            // obj.size + "<br>版本号:" + obj.version;
            updateurl = obj.url;
            fileName = obj.name+".apk";
            getVersionContent();
            // var value = "稍后;更新";
            // var mycars = value.split(";");
            // uexWindow.confirm('', '当前有新版本,是否更新&#63;', mycars);//弹出提示框,是否确定更新
        } else if (obj.result == 1) {
            //苹果
            //alert("更新地址是:" + obj.url + "<br>文件名:" + obj.name + "<br>文件大小:" +
            //obj.size + "<br>版本号:" + obj.version)
            ;// tips = "当前版本是最新的";alert(tips);
        } else if (obj.result == 2) {

        }
    };
    //检查是否已经存在sd卡的回调函数(step:3)
    uexFileMgr.cbIsFileExistByPath = function(opCode, dataType, data) {
        Log('uexFileMgr.cbIsFileExistByPath flag_sdcard='+flag_sdcard+' , data='+data);
        if (flag_sdcard == 0) {
            if (data == 0) {
                Log('sdcard不存在,根据具体情况处理');
            } else {
                //执行检查更新
                uexWidget.checkUpdate();//根据config.xml里面配置的检查更新地址发起http请求
            }
            flag_sdcard = 1;
        } 
    };
    //获取平台版本回调函数,确定是客户端是那个平台的客户端 (step:2)
    uexWidgetOne.cbGetPlatform = function(opId, dataType, data) {
        Log('uexWidgetOne.cbGetPlatform ');
        //获取系统版本信息回调函数
        platform = data;
        Log('platform= '+platform);
        if (data == 0) {
            // 是iphone
            uexWidget.checkUpdate();// 直接调用检查更新,检查更新地址在config.xml里面有配置
        } else if (data == 1) {
            // 是android
            flag_sdcard = 0;
            uexFileMgr.isFileExistByPath('/sdcard/');//先判断是否存在sd卡,再调用checkUpdate来进行更新
        } else {
            // 是平台
        }
    };
    uexWidgetOne.getPlatform();//获取平台版本 (step:1)
}
function Log(s) {

      }
    }
}

Finally, the app’s config.xml file configuration update address is filled in as:

App update tips:

The content of the pop-up window can be customized according to the content of the version.php file.

The above content is how this article explains how to use the Appcan client to automatically update the PHP version number. I hope it will be helpful to everyone.
