Best way to restrict file size/type?

[jeffkee]

I'm using the typical HTML form (<input type="file" name="picture">)

FOr teh form handling part, what I have so far is

if($submit)
	{




	//upload images

	if(file_exists($photo)){unlink($photo);}

	move_uploaded_file($_FILES['picture']['tmp_name'], $photo);

	echo  	"<br><br><br><center><font class=\"alert\">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Picture ".$pn." successfully added/replaced/deleted.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</font></center><br><br><br>";



	unset($_POST);

	echo "<META HTTP-EQUIV=\"Refresh\" CONTENT=\"2; URL=membercarcontrolpanel.php\">";

}

Now I'm wondering how I can restrict the file type to image files, under 4,000,000 bytes(4 Megabytes). Image files includes JPG, GIF images, to save space. Unless there are other common types of image formats that are size-efficient and widely used...

Thank you.

Look into the $_FILES autoglobal array and run some tests.

if($_FILES['picture']['size'] >= ....etc.
