How can I post a full URL in PHP?
For example:
I have a form allowing individuals to submit a long url. The resultant page is /index.php?url=http://www.example.com/
This is fine for short URLs, but for very long and complex URLs (like those from Google Maps) I need to know how to keep all of the data associated with variable url.
You need to percent encode the string — otherwise characters which have special meaning in URIs will have that special meaning instead of being treated as data.
http://php.net/urlencode
If users submit this data via a form, then it will be automatically encoded.
If you plan to include the URI in a link in an HTML document, then don’t forget to convert special characters to HTML entities.
