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.

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

Using
file_get_contents()
only shifts the problem instead of solving it when you don't change any of SSL's settings. But you can achieve that thru
stream_context_create
and then fiddling with the
SSL settings
. Once you did that you're also able to pass what SSL wants to protect you from.
error_reporting( E_ALL );
header( 'Content-type: text/plain' );
// The remote file to check
$sPic= 'https://picture.to/check/for/details.png';
// Does it work right away?
$aInfo= @getimagesize( $sPic );
if( $aInfo=== FALSE ) {
// No. Then a temporary file needs to be created.
if( $sTmp= tempnam( sys_get_temp_dir(), 'sig' ) ) {
// Tweaking the HTTPS options to weaken/ignore security
$hCtx= stream_context_create
( array
( 'ssl'=> array
( 'verify_peer'=> FALSE // Certificate verification
, 'verify_peer_name'=> FALSE
, 'allow_self_signed'=> TRUE
, 'SNI_enabled'=> TRUE // Multiple certificates on same IP address
// Download file
$sPayload= file_get_contents( $sPic, FALSE, $hCtx );
if( $sPayload!== false ) {
// Success: write to temporary file
if( file_put_contents( $sTmp, $sPayload ) ) {
$aInfo= @getimagesize( $sTmp );
} else die( 'Could not write to tempfile!' );
} else die( 'Could not download file!' );
// Delete temporary file
unlink( $sTmp );
} else die( 'Could not get tempfile name!' );
// Picture file details
print_r( $aInfo );
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.
