Upload image to telegra.ph with PHP - php

Question

I don't know the Python language. Can someone help me understand whether I correctly converted this to PHP? I want to upload a file to http://telegra.ph with PHP, but I don't know how to upload from PHP.
This code is an example from a Python Telegraph API wrapper library:
import requests
with open('/Users/python273/Desktop/123345.jpeg', 'rb') as f:
print(
requests.post(
'http://telegra.ph/upload',
files={'file': ('file', f, 'image/jpeg')} # image/gif, image/jpeg, image/jpg, image/png, video/mp4
).json()
)
And this is my PHP code that doesn't work. Is there something wrong?
$url = 'http://example.com/image.jpg';
$img = 'http://telegra.ph/upload/';
$ch = curl_init($url);
$fp = fopen($img, 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
When I run this code, I see the following error:
Warning: copy(telegra.ph/upload): failed to open stream: HTTP wrapper does not support writeable connections

Your code:
$img = 'http://telegra.ph/upload/';
...
$fp = fopen($img, 'wb');
PHP fopen() documentation is here http://php.net/manual/en/function.fopen.php , check what $mode parameter means. Why are you trying to open remote file for writing, if you only need to read it?
