在$ _GET变量中放置空格有什么问题 [英] What's wrong with putting spaces in $_GET variables
问题描述
如果我例如让我的url看起来像index.php?category = IT%20&%20Soft。然后我尝试打印$ _GET [类别],我只得到IT而不是IT& Soft。这里有什么问题?这让我非常沮丧。
问题不在于空格,而在于&符号。
使用%26
来代替,如下所示:
index.php ?category = IT%20%26%20Soft
&符号表示您正在开始另一个字段(如 category = IT&安培;子类别= somethingelse
)。您可以在Wikipedia上看到保留字符列表。
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.
The problem is not the spaces, but the ampersand.
Use %26
instead, like this:
index.php?category=IT%20%26%20Soft
The ampersand indicates that you are beginning another field (like category=IT&subcategory=somethingelse
). You can see a list of reserved characters on Wikipedia.
