Convert animated gif into PNG via PHP

Question

The following is the code I'm using in order to convert the GIF file into a PNG file and save it into a variable:

        $art = $_FILES["art"]["name"];
        $art_ext = pathinfo($art, PATHINFO_EXTENSION);
        if(strtoupper($art_ext)=="GIF"){
            $art =  imagepng(imagecreatefromstring(file_get_contents($_FILES["art"]["tmp_name"])), $art."png");    
        }
        if($art!=""){

        move_uploaded_file($art, "images/".$art );
    }

Also, is there a method for converting an animated gif to a static gif?

This code should work. I assume you are following the example at Convert JPG/GIF image to PNG in PHP? To convert a gif to a static jif you could honestly just rename the png file you created with your current code to jif. All modern web-browsers and applications will treat a static jif and a png the same.

To get the first frame of an animated gif, you can use imagecreatefromgif and to save as a gif, you use imagegif, so it would be:

$art =  imagegif(imagecreatefromgif($_FILES["art"]["tmp_name"]), $art."gif");

I'm still seeing this as animated – pedrum golriz Sep 02 '13 at 04:22
@pedrumgolriz According to the manual: `When reading animated GIF files into memory, only the first frame is returned in the image resource pointer.`. Are you sure you are not looking at the cached version? – jeroen Sep 02 '13 at 04:23
I'm looking at the file moved into the images folder – pedrum golriz Sep 02 '13 at 04:25
