What if file doesn't exist when'called'?

Anon

grrr

Just a quick question, I'm stuck again :-/.

I want to get the image-size from a file and then re-size it... that is working just fine. But now, what if the file doesn't exist?

So, like this:

 $file = "a-non-existing-file";
 $information = GetImageSize($file);

Is there an easy way to do this? I can manipulate the errors that come from $information in the script, but the error from GetImageSize...

I know one way that I found here on the Forum, but that takes handle-time.

thx 4 reading/thinking 🙂,

what do you want to do?

Anon

Well.. make sure the file does exist before running getimagesize()

Anon

I want to return that an image does not exist, eg. $information = "1";

...so that I can show a message and that there's no error.

Anon

Euhm...

The url's are given by users from my forum, so if they make a typo... an error occurs, and I don't want that 🙂.

Anon

And I now a way to make sure a file exists, but that takes handle-time like I said in my 1st post.

I just wanted to know if there is another way.

GetImageSize will return NULL if the file can't be opened. Prepend the function call with a @ to supress the error message and check if the returned value is an array or null.

You can use file_exist function.

bool file_exists (string filename);

Returns TRUE if the file specified by filename exists; FALSE otherwise.
