另外课程上的方法在于getImageInfo函数。
<?php
header("content-type:text/html;charset=utf-8");

fungsi getImageInfo($path) {

$data['type'] = $info['mime'];
return $data;
}
function openImg($path,$type){
suis($type){
case 'image/jpeg':
case 'image/jpg':
case 'image/pjpeg':
$img= image );
kes 'imej/png' :
kes 'imej/x-png':
$img=imagecreatefrompng($path);
patah; imagecreatefromgif($path);
break;
case 'image/ '
}
pulangkan $img;
}
//$water = 'watermark.jpeg ';
air berfungsi($img,$air,$pos=9,$tm=100){
$info=getImageInfo($img);
$logo=getImageInfo($water);
$dst=openImg($ img,$info['type']);
