将base64图像转换为jpg，然后上传到服务器不起作用

Question

I am new to base64 and I have never needed to convert it so I am not sure what is going on here. I have my base64 string in $socialmedia_image . I create a random file name with rand . I plug it into the function which I got off stack and....nothing. It does not convert or transfer over with move_uploaded_file and I have no idea who to check for an error.

Can someone tell me what I am doing wrong?

///// base64 string /////
$socialmedia_image = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUg.....";

$rand = rand(000000000000000,999999999999999);
$output_file = $rand.".jpg";

$socialmedia_image = base64_to_jpeg( $socialmedia_image, $output_file );

function base64_to_jpeg($base64_string, $output_file) {
    $ifp = fopen( $output_file, 'w' ); 
    $data = explode( ',', $base64_string );
    fwrite( $ifp, base64_decode( $data[ 1 ] ) );
    fclose( $ifp ); 
    return $output_file; 
}
move_uploaded_file($socialmedia_image, "../tickets/attachments/".$output_file);

那个怎么样？

file_put_contents($output_file, $data);
