图片上传并使用ImageMagick生成缩略图

使用ImageMagick，您可以轻松，更快地创建缩略图，比使用PHP的容易得多。

1. // Location to upload main image:
2. $mainDir = $_SERVER['DOCUMENT_ROOT'].'/images/l/';
3. // Location to create the thumb image:
4. $smalDir = $_SERVER['DOCUMENT_ROOT'].'/images/s/';
5. // Command to use:
6. $command = '/usr/bin/convert';
7. // Thumbnail width:
8. $size = 210;
9. // Make sure we have an image:
10. if(isset($_POST['submit'])){
11. if(getimagesize($_FILES['photo']['tmp_name'])){
12. $name = $_FILES['photo']['name'];
13. $uploadfile = $mainDir . $name;
14. move_uploaded_file($_FILES['photo']['tmp_name'], $uploadfile);
15. $lrgImg = $mainDir . $name;
16. $smlImg = $smalDir . $name;
17. $imageMagick = $command . " '". $lrgImg . "' -resize '$size' '" . $smlImg . "'";
18. shell_exec($imageMagick);
19. }
20. header("Location: /test.php");
21. exit;
22. }else{
23. ?>
25. foreach(glob($smalDir.'*') as $img){
26. echo ' ';
27. }
28. }
29. ?>
