TalkPHP - View Single Post - Having trouble with Custom Function "isImage"

PHP Code:


			
<?php

 function isImage($handler) {
    if(file_exists($handler)) {
        $handler == $handler.".JPG";
        $handler == $handler.".PNG";
        $handler == $handler.".GIF";
        $handler == $handler.".BMP";
 }
}

$handler = "test.bmp";

 if(isImage($handler)) {
     echo "$handler is in fact, an Image!";
} else 
   echo "$handler is not an Image!";

   

?>

It outputs $handler is not an Image when really it is!

What is the problem here!

One more thing, is it case sensitive?
