<?php

$ch = curl_init();
// 把编码后的字符串当做一个 GET 参数
$location = curl_escape($ch, 'Hofbr?uhaus / München');
// 结果： Hofbr%C3%A4uhaus%20%2F%20M%C3%BCnchen
// 用编码好的字符串组装一个 URL
$url = "http://example.com/add_location.php?location={$location}";
// 结果： http://example.com/add_location.php?location=Hofbr%C3%A4uhaus%20%2F%20M%C3%BCnchen
// 发送 HTTP 请求并关闭句柄
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)."
What is difference between this function and urlencode()?
