2，upload_file.php
-
-
//php普通文件上传
- //by bbs.it-home.org
- if ((($_FILES["file"]["type"] == "image/gif")|| ($_FILES["file"]["type"] == "image/jpeg")|| ($_FILES["file"]["type"] == "image/pjpeg"))&& ($_FILES["file"]["size"] if ($_FILES["file"]["error"] > 0) {
- echo "Return Code: " . $_FILES["file"]["error"] . "
";
- }else {
- echo "Upload: " . $_FILES["file"]["name"] . "
";
- echo "Type: " . $_FILES["file"]["type"] . "
";
- echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb
";
- echo "Temp file: " . $_FILES["file"]["tmp_name"] . "
";
-
- if (file_exists("upload/" . $_FILES["file"]["name"])){
- echo $_FILES["file"]["name"] . " already exists. ";
- }else{
- move_uploaded_file($_FILES["file"]["tmp_name"],
- "upload/" . $_FILES["file"]["name"]);
- echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
- }
- }
-
- }else {
- echo "Invalid file";
- }
- ?>
二、异步文件上传
使用iframe异步上传文件。
1，前端html
2，Js代码
-
- function startUpload() {
- var spanObj = document.getElementById("info");
- spanObj.innerHTML = " 开始上传";
- document.getElementById("upForm").sumbit();
- }
- //回调
- function stopUpload(responseText){
- var spanObj = document.getElementById("info");
- spanObj.innerHTML = "上传成功";
- spanObj.innerHTML = responseText;
- }
-
2）、服务器端代码
-
-
$file = $_FILES['myfile']; - $fileName = uploadFile($file);
- //$result = readFromFile("../upload/" . $fileName);
- echo "";
-
- function uploadFile($file) {
- // 上传路径
- $destinationPath = "../upload/";
- if (!file_exists($destinationPath)){
- mkdir($destinationPath , 0777);
- }
- //重命名
- $fileName = date('YmdHis') . '_' . iconv('utf-8' , 'gb2312' , basename($file['name']));
- if (move_uploaded_file($file['tmp_name'], $destinationPath . $fileName)) {
- return iconv('gb2312' , 'utf-8' , $fileName);
- }
- return '';
- }
//代码注释 - /*
- 1，关于basename方法
- $path = "/testweb/home.php";
- //显示带有文件扩展名的文件名
- echo basename($path);
- //显示不带有文件扩展名的文件名
- echo basename($path,".php");
-
- 2，关于iconv
- iconv('gb2312' , 'utf-8' , $fileName);//将$fileName从gb2312转为utf-8格式。
- 注：该函数需要开启php.ini里面的php_iconv.dll
-
- 3，关于$_FILES['myfile']
- $_FILES相当于一个二维数组，而$_FILES['myfile']相当于一个一维数组。所以可以
- $f = $_FILES['myfile'];
- echo $f['name'];
-
- 如果直接访问该$_FILES['myfile']，则会报Undefined index: myfile。此时加上
- if(!isset($_FILES['myfile'])){
- die('上传文件不存在！');
- }
- */
