How can find image type without extension in php?
<p>I have image upload php class. This process uploaded Images(.png,jpeg,.gif).
             I am using this function to find image type</p>

<pre><code> function getImageType($image_name){
    return end(explode('.',$mage_name));
              }
</code></pre>

<p>if someone upload any file with fake extension . error will happen. How can i Check type of image without
            checking extension?</p>
