出于某种原因，此脚本将始终输出“您的许可证密钥正确！做得好。”即使许可证密钥错误。我不知道我在这里做错了什么;它应该工作。基本上我正在尝试使用适当的参数使PHP脚本在Iframe中运行此脚本。 psh并不重要，但key是用户在通过IFrame发送请求的PHP脚本配置中输入的许可证密钥等。

包含IFrame的PHP脚本看起来像这样......

echo "<iframe height='70px' width='700px' src='http://marksrtz.site50.net/prl/main.php?key=".urlencode($license_key)."&vn=".urlencode($version)."&a=".urlencode($_SERVER['HTTP_HOST)."'></iframe>";

我很确定所有这些都是正确的，它不会输出正确的东西。

Answer 1

if($lko = TRUE) {使用条件评估为true进行赋值。请改用比较：if($lko == TRUE) {

看起来完全正常的脚本总是输出相同的东西
