由於某種原因，此腳本將始終輸出「您的許可證密鑰正確無誤！幹得好」。即使許可證密鑰錯誤。我沒有看到我在這裏做錯了什麼;它應該工作。基本上我試圖讓一個PHP腳本在iframe中運行這個腳本，並帶有適當的參數。 psh並不重要，但key是用戶在通過IFrame等發送請求的PHP腳本的配置中輸入的許可證密鑰。看起來完全正確的腳本總是輸出相同的東西

包含IFRAME的PHP腳本看起來像這樣...

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>";

我敢肯定，這一切是正確的，它只是不會輸出正確的事情。

if($lko = TRUE) {如果條件評估爲true，則進行分配。改爲使用比較：if($lko == TRUE) {

YAAAAH！這就是我玩遊戲幾天，然後做PHP的。我現在必須重新學習PHP。感謝您發現錯誤。 – unknownA 2015-04-05 17:15:24
