Ejemplo #1 Ejemplo de image_type_to_mime_type()
<?php
header("Content-type: " . image_type_to_mime_type(IMAGETYPE_PNG));
?>Nota: Esta función no requiere la biblioteca GD.
If you are working with Images only and you need mime type (e.g. for headers), then this is a fast and reliable technique:
<?php
$file = 'path/to/image.jpg';
$image_mime = image_type_to_mime_type(exif_imagetype($file));
?>
It will output true image mime type even if you rename your image file.
