我写了一个实现下载功能的php文件,但是有问题,大家帮忙看下,我是新手,刚刚接触php,急着交作业,忘指点!<?php
$file_name = "audiQ5320x240.avi";
$file_dir = "video/";
if (!file_exists($file_dir . $file_name)) { //检查文件是否存在
echo "文件找不到";
exit;
} else {
$file = fopen($file_dir . $file_name,"r"); // 打开文件
// 输入文件标签
header("content-type: application/avi");
header("accept-ranges: bytes");
header("accept-length: ".filesize($file_dir . $file_name));
header("content-disposition: attachment; filename='$file_name'");
// 输出文件内容
echo fread($file,filesize($file_dir . $file_name));
fclose($file);
exit;}
?>还有就是视频文件和php文件分别在站点下的video和php文件夹中,路径这样写对不对?如果有错,把正确的代码给我一份吧,谢谢了哈!
$file_name = "audiQ5320x240.avi";
$file_dir = "video/";
if (!file_exists($file_dir . $file_name)) { //检查文件是否存在

比如把上面的代码存成down.php
那么在html中 调用 down.php?file=audiQ5320x240.avi
