你可以通過使用使這更簡(jiǎn)單in_array()
在標(biāo)簽上 soecify 一個(gè)方法也是一個(gè)好主意<form>。默認(rèn)值可能是 GET，但如果您對(duì)其進(jìn)行編碼，那么您就是在自我記錄您的代碼。

我終于想通了這個(gè)問題！我分配了一個(gè)變量GET并用這個(gè)變量代替了GET所有地方。這似乎解決了問題！

$_GET是輸入?yún)?shù)數(shù)組（來自 url）。您必須按名稱取值：
$_GET['guess']
if($countries[$x]==$_GET['guess'])
并使用逗號(hào)連接字符串：
echo 'Your country ' . $_GET['guess'] . ' is valid!';
