Best way to encode special chars in url

Question

What is the best way to encode special characters in a url? Let's say I pass an variable from javascript to a php script that way:

http://example.com/my sp3c!al var!a$le

What is the best way to encode that special characters (like whitespace, !, $, /, \\ etc.)? Is there a method in javascript to encode it with a corresponding function in php to decode it there?

Answer 1

您需要使用encodeURIComponent(yourvar);

Answer 2

You can do it in three ways

encodeURI(yourvar) output http://example.com/my%20sp3c!al%20var!a$le

amd

encodeURIComponent(yourvar)

output http%3A%2F%2Fexample.com%2Fmy%20sp3c!al%20var!a%24le

escape()

output http%3A//example.com/my%20sp3c%21al%20var%21a%24le

using escape is not recomended because it is deprecated since ECMAScript v3.

functions is for JavaScript escaping, not HTTP.
