PHP create image from application/octet stream

Question

My application is having images sent to it from mobile devices with the content-type \"application/octet-stream\".

I need to process these images using the GD librar

Answer 1

I found this in the codeigniter forum a way to change the mime and it works, I suppose you can use for other frameworks as well, this is the link and this the code:

//if mime type is application/octet-stream (psp gives jpegs that type) try to find a   more specific mime type

$mimetype = strtolower(preg_replace("/^(.+?);.*$/", "\\1", $_FILES['form_field']  ['type'])); //reg exp copied from CIs Upload.php

if($mimetype == 'application/octet-stream'){
    $finfo = finfo_open(FILEINFO_MIME, '/usr/share/file/magic');
    if($finfo){
    $_FILES['form_field']['type'] = finfo_file($finfo, $_FILES['form_field']['tmp_name']);
    finfo_close($finfo);
    }
    else echo "finfo_open() returned false");
}  

Fileinfo extension needs to be installed on the server.

It worked for me.

Answer 2

Easy :)

$image = imagecreatefromstring( $data );

Specifically:

$data = file_get_contents($_FILES['myphoto']['tmp_name']);
$image = imagecreatefromstring( $data );

Answer 3

you can use this function too. it not require any other dependency. and work perfectly for other types also.

function _getmime($file){
    if($info = @getimagesize($file)) {
        return image_type_to_mime_type($info[2]);
    } else {
        return mime_content_type($file);
    }
}
