如何从$

如何从$ _REQUEST - 正则表达式获得加号的符号？(How to get the symbol of plus as it is from $_REQUEST - regular expressions?)

如何在传递$ _REQUEST时传递plus +符号？

例如，我想通过这个，

xxx.php?key=xPo8lUEXpqg8bKL+32o6yIOK

我想在echo $ _REQUEST ['key']中获得xPo8lUEXpqg8bKL+32o6yIOK ; 但我会在下面得到这个 -

xPo8lUEXpqg8bKL 32o6yIOK

我应该怎么做才能解决这个问题？ 正则表达式再次？

谢谢。

How to pass the symbol of plus + as it is when you want to pass it into $_REQUEST?

For instance, I want to pass this,

xxx.php?key=xPo8lUEXpqg8bKL+32o6yIOK

and I want to get xPo8lUEXpqg8bKL+32o6yIOK in echo $_REQUEST['key']; but I will get this below instead -

xPo8lUEXpqg8bKL 32o6yIOK

What should I do to fix this? Regular expressions again??

Thanks.

您需要使用%2B而不是+ ，因为+是空间的URL编码符号。 一般来说，你应该使用urlencode()来正确地转义事物：

$url = "xxx.php?key=" . urlencode('xPo8lUEXpqg8bKL+32o6yIOK');

You need to use %2B instead of +, as + is the URL-encoded symbol for a space. In general, you should use urlencode() to escape things properly:

$url = "xxx.php?key=" . urlencode('xPo8lUEXpqg8bKL+32o6yIOK');
