为什么我会为简单的if和switch语句得到解析错误

Question

有谁能告诉我为什么我会为这些简单的代码得到解析错误？ 我使用的PHP版本是5.5.12。

<?php
$favcolor = "red";

switch ($favcolor) {
    case "red":
        echo "Your favorite color is red!";
        break;
    case "blue":
        echo "Your favorite color is blue!";
        break;
    case "green":
        echo "Your favorite color is green!";
        break;
    default:
        echo "Your favorite color is neither red, blue, nor green!";

}

?>

（！）解析错误：第5行的语法错误，意外的'Â'（T_STRING），期待案例（T_CASE）或默认（T_DEFAULT）或'}'

<?php
// define variables and set to empty values
$nameErr = $emailErr = $genderErr = $websiteErr = "";
$email = $gender = $comment = $website = "";

$MyVar = $_SERVER["REQUEST_METHOD"];
echo $_SERVER["REQUEST_METHOD"];

if ($MyVar == "GET") {
    echo "This is it.\n";

}


}

?>

（！）解析错误：语法错误，第18行意外的'{'

Answer 1

第一个代码是完全正确的！

第二个，你已经增加了额外的＆＃39;}＆＃39;在文件的最后。只需使用：

<?php
// define variables and set to empty values
$nameErr = $emailErr = $genderErr = $websiteErr = "";
$email = $gender = $comment = $website = "";

$MyVar = $_SERVER["REQUEST_METHOD"];
echo $_SERVER["REQUEST_METHOD"];

if ($MyVar == "GET") {
    echo "This is it.\n";
}

或

<?php
// define variables and set to empty values
$nameErr = $emailErr = $genderErr = $websiteErr = "";
$email = $gender = $comment = $website = "";

$MyVar = $_SERVER["REQUEST_METHOD"];
echo $_SERVER["REQUEST_METHOD"];

if ($MyVar == "GET")
    echo "This is it.\n";
