Example #1 curl_escape() example
<?php
// Create a curl handle
$ch = curl_init();
// Escape a string used as a GET parameter
$location = curl_escape($ch, 'Hofbräuhaus / München');
// Result: Hofbr%C3%A4uhaus%20%2F%20M%C3%BCnchen
// Compose an URL with the escaped string
$url = "http://example.com/add_location.php?location={$location}";
// Result: http://example.com/add_location.php?location=Hofbr%C3%A4uhaus%20%2F%20M%C3%BCnchen
// Send HTTP request and close the handle
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
curl_close($ch);

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)."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.
