Message Getimagesize() Function.getimagesize Read Error Codeigniter
Like you said, if used on a non-existing file, getimagesize generates a warning : This code : if ($data = getimagesize('not-existing.png')) { echo "OK"; } else { echo "NOT OK"; } will get you a Warning: getimagesize(not-existing.png) [function.getimagesize]: failed to open stream: No such file or directory A solution would be to use the @ operator, to mask that error : if ($data = @getimagesize('not-existing.png')) { echo "OK"; } else { echo "NOT OK"; } As the file doesn't exist, $data will still be false ; but no warning will be displayed. Another solution would be to check if the file exists, before using getimagesize ; something like this would do : if (file_exists('not-existing.png') && ($data = getimagesize('not-existing.png')) ) { echo "OK"; } else { echo "NOT OK"; } If the file doesn't exist, getimagesize is not called -- which means no warning Still, this solution is not the one you should use for images that are on another server, and accessed via HTTP (if you are in this case), as it'll mean two requests to the remote server. For local images, that would be quite OK, I suppose ; only problem I see is the notice generated when there is a read error not being masked. Finally : I would allow errors to be displayed on your developpement server, And would not display those on your producti

(Security must be paramount!!) From what I have read online, using getImageSize() is the easiest and most reliable way to check what File Type an uploaded file actually is. According to the PHP Manual... The getimagesize() function will determine the size of any given image file and return the dimensions along with the file type and a height/width text string to be used inside a normal HTML IMG tag and the correspondant HTTP content type. On failure, FALSE is returned. When I try to upload a non-Image FIle I am getting inconsistent issues... Here is a snippet of my code...

If you don't have complete control of your hosting environment, you don't know what you can expect in the way of error handling if you don't do everything you can think of.One method I use in all of my programming is to place an '@' character in front of function calls that have potential for returning warnings or errors.@require($_SITE['ROOT'].$_FOLDERS['CONTROL'].'logger.php'); // suppress a file not found error @mysql_connect($host,$user,$pass); // suppress no connection error I recommend using the @ once your website is in production. I generally don't use the @ on development servers because I want to be aware of errors during development.
