PHP function getimagesize() gives “Read error” when trying to get https url

问题

I am trying to use getimagesize with URL and with http everything is fine. However when trying to use function on https url I am getting "Read error" Notice and false as result. I checked and I have OpenSSL 0.98 installed on the server (so it should be working with https as well). I know that I can download the image first and then use it but it seems to me like this should work and that I am missing something. Could you please provide me with some solution (other than downloading the image first and then opening it) ?

Thank you in advance.

回答1:

You can use file_get_contents() as an alternate solution..

<?php
$filename='something';
file_put_contents($filename,file_get_contents($url));
$size = getimagesize($filename);
var_dump($size);

Updating OpenSSL may solve your problem.

Judging from the OpenSSL version you report you have on server this problem may be caused by the server having a newer version of SSL than your client.

The Facebook server is probably using a version >= 1.0.0 or a custom SSL library, while you are using an old 0.9.8.

Heartbeat overflow issue forced many webservers to update their OpenSSL version.

A random article about OpenSSL 1.0.0 handshake issues with clients using 0.9.8 version:
