发送Facebook图片网址作为参数

Question

Facebook image url for user profile looks like

https://scontent.xx.fbcdn.net/hprofile-xfa1/v/t1.0-1/c26.26.321.321/s50x50/1004031_160695494109373_202362495_n.jpg?oh=bc24275f3c0b63adcd7f2

I want to send this url in request to server

$FBImageUrl = "https://scontent.xx.fbcdn.net/hprofile-xfa1/v/t1.0-1/c26.26.321.321/s50x50/1004031_160695494109373_202362495_n.jpg?oh=bc24275f3c0b63adcd7f2";
$postString = "http://example.com/script.php?img_url=" . FBImageUrl;

But what will happen if this url have question mark inside?

Answer 1

use urlencode()

$FBImageUrl = "https://scontent.xx.fbcdn.net/hprofile-xfa1/v/t1.0-1/c26.26.321.321/s50x50/1004031_160695494109373_202362495_n.jpg?oh=bc24275f3c0b63adcd7f2";
$postString = "http://example.com/script.php?img_url=".urlencode($FBImageUrl) ;

In your script.php

$img_url = urldecode($_GET['img_url']);
