Please someone add an example for escaping ampersands between parameters.
E.g. what is the correct approach for using this URL with curl:
https://example.com/?p1=1&p2=2&p3=3
This is not obvious, and needs explanation.
(PHP 5 >= 5.5.0, PHP 7, PHP 8)

This is not obvious, and needs explanation.This function is strictly equivalent to rawurlencode().
Internally it uses curl_easy_escape() from libcurl, whose doc says: "This function converts the given input string to an URL encoded string (…). All input characters that are not a-z, A-Z, 0-9, '-', '.', '_' or '~' are converted to their "URL escaped" version (%NN where NN is a two-digit hexadecimal number)."
