Image size checking

[michuk]

I have an image checking function but it seems to work with the local files only. How to enhance it so that I can check the size of files on remote servers as well? Hope to hear some good tips!

The function looks like this:

function checkImage($picture_url)
{

$fp=fopen($picture_url, "rb");

if($fp)
{
     $size = getimagesize ("$picture_url");

 if ($size[0]<150 && $size[1]<150 && $picture_url!=null)
 {
    print("picture size ok!");
    return true;
 }
 else 
 {
  print("picture size NOK!");
  return false;
 }
}
else
{
  print("no picture!");
  return false;
}

return true;

}

Try changing the string mode to: "r" from "rb". Also, ive never used getimagesize(). I use a different method. But doesnt it read files in bytes?

[michuk]

No, I tried it already. It seems like it doesn't know anything about remote files....
I dunno if it reads binary. There's nutting about it in docs. What f-ction do you use?

I simply use the filesize() function. It reads in bytes.

filesize("path/filename");

You can still use your conditionals in your function to determine what filesize is allowed. Remember it reads in bytes!

I dont think filesize() can be used to read remote files. Look into the fread() function.
