PHP上传图片的简单例子(入门参考)

2、admin_upfile.php

4. date_default_timezone_set('PRC');
5. //这里上传 $upsize判断上传文件的大小
6. $uppath = isset($_REQUEST["upPath"]) ? $_REQUEST["upPath"] : "/attached/"; //文件上传路径
7. $formName = isset($_REQUEST["formName"]) ? $_REQUEST["formName"] : "myform"; //回传到上页面编辑框所在Form的Name
8. $editName = isset($_REQUEST["editName"]) ? $_REQUEST["editName"] : $_REQUEST["editName"]; //回传到上页面编辑框的Name
9. //转换根目录的路径
10. if (strpos($uppath, "/") == 0) {
11. $i = 0;
12. $thpath = $_SERVER["SCRIPT_NAME"];
13. $thpath = substr($thpath, 1, strlen($thpath));
14. while (strripos($thpath, "/") !== false) {
15. $thpath = substr($thpath, strpos($thpath, "/") + 1, strlen($thpath));
16. $i = ++$i;
17. }
19. $pp = "";
20. for ($j = 0; $j < $i; ++$j) {
21. $pp .="../";
22. }
24. $uppaths = $pp . substr($uppath, 1, strlen($thpath));
25. }
26. $filename = date("y-m-d");
27. if (is_dir($uppaths . $filename) != TRUE)
28. mkdir($uppaths . $filename, 0777);
29. // if(is_dir($filename."/".$ctime)!=TRUE) mkdir($filename."/".$ctime,0777);
31. $f = $_FILES['file1'];
33. if ($f["type"] != "image/gif" && $f["type"] != "image/pjpeg" && $f["type"] != "image/jpeg" && $f["type"] != "image/x-png") {
34. echo "";
35. //echo $f['type'];
36. return false;
37. }
40. //获得文件扩展名
41. $temp_arr = explode(".", $f["name"]);
42. $file_ext = array_pop($temp_arr);
43. $file_ext = trim($file_ext);
44. $file_ext = strtolower($file_ext);
46. //新文件名
47. $new_file_name = md5(date("YmdHis")) . '.' . $file_ext;
48. //$new_file_name = md5(date("YmdHis") . '_' . rand(10000, 99999)) . '.' . $file_ext;
50. $dest = $uppaths . $filename . "/" . date("ymdhis") . "_" . $new_file_name; //设置文件名为日期加上文件名避免重复 上传目录
51. $dest1 = $uppath . $filename . "/" . date("ymdhis") . "_" . $new_file_name; //设置文件名为日期加上文件名避免重复
52. $r = move_uploaded_file($f['tmp_name'], $dest);
53. if ($f['size'] > 0) {
55. echo "";
56. echo "";
57. }
58. ?>

3、admin_upload.php

6. $uppath = isset($_REQUEST["upPath"]) ? $_REQUEST["upPath"] . "/" : "/attached/"; //文件上传路径
7. $formName = isset($_REQUEST["formName"]) ? $_REQUEST["formName"] : "myform"; //回传到上页面编辑框所在Form的Name
8. $editName = isset($_REQUEST["editName"]) ? $_REQUEST["editName"] : $_REQUEST["editName"]; //回传到上页面编辑框的Name
9. ?>
