有什么想法吗？我发现你的代码也有同样的错误。当我删除htmlentities函数时，它工作得很好
<?php
header('Content-Type: text/xml');
print('<?xml version="1.0" encoding="UTF-8"?>
<bbcodes>
<block>
<pattern><![CDATA[<p.*?>]]></pattern>
<replace><![CDATA[[p]]]></replace>
</block>
<block>
<pattern><![CDATA[</p>]]></pattern>
<replace><![CDATA[[/p]]]></replace>
</block>
</bbcodes>');
?>
我收到了与您的代码相同的错误。当我删除htmlentities函数时，它工作得很好
<?php

<pattern><![CDATA[<p.*?>]]></pattern>
