php - 语法错误 - 意外的“：”

Question

我的 php 脚本根据按下的提交按钮指向一个 url。但是，当我运行测试时，我收到一条错误消息，指出第 4 行包含意外的“：”，但我的第 4 行是带有 url 的标题脚本？

我很困惑，因为我还有其他类似的脚本，但他们没有给我那个错误。谁能告诉我我错过了什么，可能很简单，我之前被抓到很简单。

<?php
if ($_REQUEST['Dish1'] == 'Dish1')
{
header(“Location: http://blahblah”.urlencode($_POST[‘uid’]));
}
else if ($_REQUEST['Dish1'] == 'Dish2')
{
header(“Location: http://blahblah2”.urlencode($_POST[‘uid’]));
}
else if ($_REQUEST['Dish1'] == 'Dish3')
{
header(“Location: http://blahblah3”.urlencode($_POST[‘uid’]));
}
etc.....
?>

Answer 2

You are using the wrong quotes... use "" instead of “”. Refer to Wikipedia, you must use typewriter quotes, not curly or inverted commas.

PD: Also PHP Parse error: syntax error, unexpected '.' on line 15 ; )

Answer 3

Replace you code with following

<?php

if ($_REQUEST['Dish1'] == 'Dish1')
{
header("Location: http://blahblah.urlencode".($_POST['uid']));
}
else if ($_REQUEST['Dish1'] == 'Dish2')
{
header("Location: http://blahblah2".urlencode($_POST['uid']));
}
else if ($_REQUEST['Dish1'] == 'Dish3')
{
header("Location: http://blahblah3".urlencode($_POST['uid']));
}

?>

Answer 4

Is it not much easier to write:

$lookup = array('Dish1' = > 'http://blba1', 'Dish2' = > 'http://blba2');

if( isset($lookup[$_REQUEST['Dish1']]))
  header("Location: " . $lookup[$_REQUEST['Dish1']]);
