Question

无论如何我可以在html文件中使用这段代码吗？

我已经尽了一切努力，似乎无法让它发挥作用......

非常感谢任何帮助..谢谢！

$isUDIDProtected=TRUE;
$compatibleVersions=array("8.1.1","8.1","8.0");

我是每个php文件的顶级代码

if ($isUDIDProtected)
{
        echo "<p style=\"color: red;\">This package is UDID protected! You must have your device registered to download this package</p>";
    }

    if ($compatibleVersions) 
{
        $uaString = $_SERVER["HTTP_USER_AGENT"];
        if (preg_match("/(.*) OS ([0-9]*)_([0-9]*)_([0-9]*) (.*)/", $uaString)) {
            $version = preg_replace("/(.*) OS ([0-9]*)_([0-9]*)_([0-9]*) (.*)/","$2.$3.$4", $uaString);
        } else if (preg_match("/(.*) OS ([0-9]*)_([0-9]*) (.*)/", $uaString)) {
            $version = preg_replace("/(.*) OS ([0-9]*)_([0-9]*) (.*)/","$2.$3", $uaString);
        }
        if ($version) {
            if (in_array($version, $compatibleVersions)) {
                echo "<p style=\"color: green;\">This package is compatible with your iOS version :)</p>";
            } else {
                echo "<p style=\"color: #FFCC00\">This package is not comfirmed to work on your iOS version</p>";
            }
        }
    }

html文件位于

之下

<ul data-role="listview" data-inset="true">
<li data-role="list-divider"><center>Compatibility</center></li>
<li><center>(show yes or no)</center></li>
</ul>

你需要根据if else构造情况在html代码中的php开启和关闭标签下添加php代码。

您的代码是PHP代码。它不会在＆＃34; html＆＃34;内部工作。文件。您需要将其放在PHP文件中（带有相应的php标记）并通过服务器运行它。说到这里，你可以得到一个＆＃34; compat.php＆＃34;文件包含代码：

$compatibleVersions=array("8.1.1","8.1","8.0");

    if ($compatibleVersions) 
{
        $uaString = $_SERVER["HTTP_USER_AGENT"];
        if (preg_match("/(.*) OS ([0-9]*)_([0-9]*)_([0-9]*) (.*)/", $uaString)) {
            $version = preg_replace("/(.*) OS ([0-9]*)_([0-9]*)_([0-9]*) (.*)/","$2.$3.$4", $uaString);
        } else if (preg_match("/(.*) OS ([0-9]*)_([0-9]*) (.*)/", $uaString)) {
            $version = preg_replace("/(.*) OS ([0-9]*)_([0-9]*) (.*)/","$2.$3", $uaString);
        }
        if (isset($version) && in_array($version, $compatibleVersions)) {
           echo "<p style=\"color: green;\">This package is compatible with your iOS version :)</p>";
        } else {
           echo "<p style=\"color: #FFCC00\">This package is not comfirmed to work on your iOS version</p>";
        }
    }

然后，在另一个文件＆＃34; htmlPage.php＆＃34;里面，像：

<?php 
$isUDIDProtected=TRUE;
if ($isUDIDProtected)
{
        echo "<p style=\"color: red;\">This package is UDID protected! You must have your device registered to download this package</p>";
die();
    }
?>
<ul data-role="listview" data-inset="true">
<li data-role="list-divider"><center>Compatibility</center></li>
<li><center><?php include "compat.php" ?></center></li>
</ul>
