php实现网页常见文件上传功能
用php实现网页常见的文件上传功能,供大家参考,具体内容如下
上传页面
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <!--上传文件 enctype="multipart/form-data"指的是编码方式为上传多种类型文件和数据流--> <form method="post" action="123.php" enctype="multipart/form-data"> <input type="file" name="file"> <input type="submit" value="上传"> </form> </body> </html>
文件处理页面
<?php /** * Created by fcc * User: Administrator * Date: 2017/10/31 * Time: 10:33 */ var_dump($_FILES); //文件处理要实现的几点 //1.是否有错误 //2.文件类型是否符合要求 //3.文件大小是否符合要求 //4.文件名是否重复 //$types = ['image/jpeg','image/png']; if (!$_FILES['file']['error']){ if ($_FILES['file']['type'] == 'image/jpeg'){ if ($_FILES['file']['size']<200000){ //文件传到文件夹中,可以拼接时间戳,用户名等防止文件名重复 $file_name = "./upload/2017-10-31/".$_FILES['file']['name']; if (!file_exists($file_name)){ move_uploaded_file($_FILES['file']['tmp_name'],$file_name); // $filename=iconv("UTF-8","",$file_name); }else{ echo "文件名重复"; } }else{ echo "文件过大"; } }else{ echo "文件格式错误"; } } //实验过程中出现因为图片汉字命名报错!!!
