How is URL encoding handled in different programming languages?

How is URL encoding handled in different programming languages?

URL encoding, also known as percent encoding, is used to encode special characters in URLs. Different languages have their own libraries or functions for this. For example, in JavaScript, you can use encodeURIComponent(), while in Python, you can use urllib.parse.quote().

Can you give me examples in Python and JavaScript?

Sure! In Python, you would do:

import urllib.parse
encoded_url = urllib.parse.quote('https://example.com/?name=John Doe')

In JavaScript, it looks like this:

const encodedUrl = encodeURIComponent('https://example.com/?name=John Doe');

What about in PHP?

In PHP, you can use the urlencode() function. Here's an example:

$encodedUrl = urlencode('https://example.com/?name=John Doe');

Are there any differences in how these languages handle spaces?

Yes, in URL encoding, spaces are typically encoded as %20. However, in some languages like JavaScript, spaces can also be encoded as +. It's important to be aware of these differences when working across languages.
