HTML内的PHP兼容性检查

Question

无论如何，我可以在html文件中使用此代码吗？

我已经尝试了所有可能的方法，但似乎无法使其正常工作...

任何帮助将不胜感激..谢谢！

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

我是每个php文件的最高代码

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文件在下面

<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>

Answer 1

您需要根据是否构造情况，在html代码中的php打开和关闭标签下添加php代码。

Answer 2

您的代码是PHP代码。 它无法在“ html”文件中运行。 您需要将其放在一个PHP文件（带有相应的php标记）中，并通过服务器运行它。 话虽如此，您可能会有一个带有代码的“ 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：

<?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>
