PHP URL GET parameters inside URL parameter

Question

I am developing facebook/myspace content share buttons. The Facebook link takes you to a URL on my website, but I need to pass additional parameters to my URL along with the parameters passed to facebook. Here's my example:

http://www.facebook.com/share.php?t=MyCompany&u=http://foobar.com/test7.php?Share=161&FbShare=Facebook28

Do I need to escape something inside the "u" parameter?

Answer 1

你应该可以做（http://php.net/manual/en/function.urlencode.php）。

$url = 'http://www.facebook.com/share.php?t=MyCompany&u='.urlencode('http://foobar.com/test7.php?Share=161&FbShare=Facebook28');

Answer 2

You need to use urlencode on the u parameter, which will result in your URL looking like this:

http://www.facebook.com/share.php?t=MyCompany&u=http%3A%2F%2Ffoobar.com%2Ftest7.php%3FShare%3D161%26FbShare%3DFacebook28
