HTML内部的PHP兼容性检查 - PHP Compatibility Check Inside HTML

PHP Compatibility Check Inside HTML

本文关键字：兼容性检查 PHP 内部 HTML | 更新日期: 2023-09-27

是否可以在html文件中使用此代码？

我已经尽了一切可能，但似乎无法奏效。。。

如有任何帮助，我们将不胜感激。。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文件位于下方

<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>

您的代码是PHP代码。它在"html"文件中不起作用。您需要将它放在一个PHP文件中(带有相应的PHP标记(，并在服务器上运行它。话虽如此，您可以有一个代码为的"compat.php"文件

$compatibleVersions=array("8.1.1","8.1","8.0");
    if ($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"htmlPage.php"中，类似于：

<?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>

您需要根据if-else构造情况，在html代码中的php打开和关闭标记下添加php代码。
