1、新建一个表单，用于上传文件的。<!DOCTYPE html><html><head> <meta charset="utf-8"/> <title>上传文件</title></head><body> <form action="upload_file.php" method="post" enctype="multipart/form-data"> <label for="file">Filename</label> <input type="file" name="file" id="file"></br> <input type="submit" value="提交"></br> </form></body></html>
3、如果上传的文件有错误就显示错误。
5、显示文件的大小。echo "type:".$_FILES['file']['type']."<br/>";
7、在浏览器进行测试。完整代码如下：<?php header("Content-type:text/html;charset=utf-8"); if($_FILES['file']['error']>0){ echo $_FILES['file']['error']."<br/>"; } else{ echo "uoload:".$_FILES['file']['name']."<br/>"; echo "type:".$_FILES['file']['type']."<br/>"; echo "size:".$_FILES['file']['size']."<br/>"; echo "store in:".$_FILES['file']['tmp_name']."<br/>"; }?>
