timing out a non-streaming function

[marcnyc]

Hello, I was wondering if there is a way to timeout a getimagesize() function so that if the image cannot be found the script doesn hang in there for a while and returns an error after, say, 2 seconds...
I tried reading in the manual about stream_set_timeout() but it seems like that can only be used with streams not with functions.

I have used a simple way to do it. I just check before calling the getimagesize() function if the file exists, with an if (file_exists....)

thanks for the suggestion, I guess it makes sense, unless file_exists() hangs too if a file doesn't exist...

it will not hang if you give an else option
here is an example;
if the image exists it resize the image to 1/3 of the original
if the image does not exist it shows another image (if the book cover is not found a general cover is shown)

  if (@file_exists("books/".$row["isbn"].".jpg"))
  {
    $size = GetImageSize("books/".$row["isbn"].".jpg");
    if($size[0]>0 && $size[1]>0)
    {
    $title = "<img src=\"books/".($row["isbn"]).".jpg\" border=1"."width = ". $size[0]/3 ." height = " .$size[1]/3 . ">";

    do_html_url($url, $title);
    }
  }
  else
  {
    echo "<img src=\"books/no_cover1.gif\">";
  }

Yes I have an else in my function so it should work... I'll test it soon (I need to finish coding the other part of this project in order to be able to test this). Thanks again.
