是否可以在PHP $ _GET vars中保存加号而不进行编码？ [英] Is it possible to preserve plus signs in PHP $_GET vars without encoding?

问题描述

请问这个网址：

http://mydomain.com/script.php?var=2+2

$ _ GET ['var']现在将是： 2 2其中应该是2 + 2

$_GET['var'] will now be: "2 2" where it should be "2+2"

显然，我可以在发送之前对数据进行编码，然后对其进行解码，但我想知道这是否是只有解决方案我也可以用加号替换空格，但我也想允许空格。我只想要任何字符被传递，没有任何url解码或编码。谢谢！

Obviously I could encode the data before sending and then decode it, but I'm wondering if this is the only solution. I could also replace spaces with plus symbols, but I want to allow spaces as well. I simply want whatever characters were passed, without any url decoding or encoding going on. Thank you!

推荐答案

当然。你可以读出 $ _ SERVER [QUERY_STRING] ，分解自己，然后放弃通常的URL解码，或者只转换％xx placeholder back。

Of course. You could read out $_SERVER["QUERY_STRING"], break it up yourself, and then forgo the usual URL decoding, or only convert %xx placeholders back.

preg_match_all('/(\w+)=([^&]+)/', $_SERVER["QUERY_STRING"], $pairs);
$_GET = array_combine($pairs[1], $pairs[2]);

（示例仅适用于字母数字参数，不执行上述的％xx解码。原始输入。）

(Example only works for alphanumeric parameters, and doesn't do the mentioned %xx decoding. Just breaks up the raw input.)
