Check image type if renamed from .png to .jpg
Question by John
If it possible to check if the type of image if it was renamed from .png to .jpg?
I need this because when I use a resize function my website stop working if the uploaded image was renamed from .png to .jpg (I made my code to accept only .jpg images)

getimagesize will contain info about image type:
$info = getimagesize('file.png');
if($info[2] == IMAGETYPE_JPEG){
}

You can always read the image type to check an image using exif_imagetype()
$image_type = exif_imagetype($filename);
Example:
<?php
if (exif_imagetype('image.gif') != IMAGETYPE_GIF) {
echo 'The picture is not a gif';
}
?>
