在 $_GET 变量中放置空格有什么问题 [英] What's wrong with putting spaces in $_GET variables

问题描述

例如，如果我的网址看起来像 index.php?category=IT%20&%20Soft.然后我尝试打印$_GET[category]"，我只得到IT"而不是IT & Soft".这里有什么问题?这让我很沮丧.

If I for example have my url looking like index.php?category=IT%20&%20Soft. Then i try to print "$_GET[category]" i only get "IT" and not "IT & Soft". What is wrong here? It's frustrating me.

推荐答案

问题不在于空格，而在于符号.

The problem is not the spaces, but the ampersand.

改用%26，像这样:

index.php?category=IT%20%26%20Soft

&符号表示您正在开始另一个字段(例如 category=IT&subcategory=somethingelse).您可以查看维基百科上的保留字符列表.

The ampersand indicates that you are beginning another field (like category=IT&subcategory=somethingelse). You can see a list of reserved characters on Wikipedia.
