我試圖將一個字符串作為用戶輸入的表單，并使用一組國家/地區檢查它是否是一個國家/地區。我現在收到此錯誤：語法錯誤，意外的“”（T_ENCAPSED_AND_WHITESPACE），期待“-”或標識符（T_STRING）或變量（T_VARIABLE）或數字（T_NUM_STRING）<html><head></head><body><h1> Welcome to the Country Searcher </h1><form method="get"> <p><label for="guess">Input Guess</label> <input type="text" name="guess" id="guess"/></p> <input type="submit"/></form><?php $countries = array("Afghanistan", "Albania", "Algeria", "American Samoa", "Andorra", "Angola", "Anguilla", "Antarctica", "Antigua and Barbuda", "Argentina", "Armenia", "Aruba", "Australia", "Austria", "Azerbaijan", "Bahamas", "Bahrain", "Bangladesh", "Barbados", "Belarus", "Belgium", "Belize", "Benin", "Bermuda", "Bhutan", "Bolivia", "Bosnia and Herzegowina", "Botswana", "Bouvet Island", "Brazil", "British Indian Ocean Territory", "Brunei Darussalam", "Bulgaria", "Burkina Faso", "Burundi", "Cambodia", "Cameroon", "Canada", "Cape Verde", "Cayman Islands", "Central African Republic", "Chad", "Chile", "China", if( in_array("$_GET['guess']", $countries)) { echo "Your country $_GET['guess'] is valid!"; } else { echo "I'm sorry!

你可以通過使用使這更簡單in_array()
在標簽上 soecify 一個方法也是一個好主意<form>。默認值可能是 GET，但如果您對其進行編碼，那么您就是在自我記錄您的代碼。
<html>

<body>
<h1> Welcome to the Country Searcher </h1>
<form method="get">
<p><label for="guess">Input Guess</label>
<input type="text" name="guess" id="guess"/></p>
<input type="submit"/>
</form>

$_GET是輸入參數數組（來自 url）。您必須按名稱取值：
$_GET['guess']
if($countries[$x]==$_GET['guess'])
并使用逗號連接字符串：
echo 'Your country ' . $_GET['guess'] . ' is valid!';
