$_SERVER['QUERY_STRING'] results in $ _SERVER ['QUERY_STRING']的结果

q=my+search+term

while $_GET['q'] results in 而$ _GET ['q']结果

my search term

How can I get 我怎样才能得到

my+search+term

does it have to be regex? 必须是正则表达式吗？

Answer 1

urlencode($_GET['q']);

Answer 2

No, you can use str_replace : 不，您可以使用str_replace ：

$str = str_replace(' ', '+', $str);

but if there are more special characters, urlencode is the better choice: 但是如果有更多特殊字符，则urlencode是更好的选择：

$str = urlencode($str);

Answer 3

$q = str_replace(' ', '+', $_GET['q'])

要么

$q = urlencode($_GET['q']);

Answer 4

$clean = urldecode($_SERVER['QUERY_STRING']); $ clean = urldecode（$ _ SERVER ['QUERY_STRING']）;
