How to implement video upload in php

How to upload video in php: first open the "php.ini" configuration file and modify the relevant parameters; then use "XHR2" to cut and upload the file; then move the video file to the desired location ;Finally add the video to the database.

php video upload is super simple

First of all, because videos are generally relatively large, we have to modify the PHP configuration first: here are two methods:

Method 1: Open: php.ini

Modify the upload configuration inside, find the following parameters, and modify them in order

file_uploads = On
  upload_tmp_dir = "d:/fileuploadtmp"
  upload_max_filesize = 50M
  post_max_size = 100M
  max_execution_time = 600
  max_input_time = 600
  memory_limit = 128M

Method 2: Use php functions to modify

ini_get() to get php .ini setting value

ini_set() sets php.ini

Suppose you want to upload a large file of 50M. Configure php.ini as follows:

file_uploads = On
 upload_tmp_dir = "d:/fileuploadtmp"
 upload_max_filesize = 50M
 post_max_size = 100M
 max_execution_time = 600
 max_input_time = 600
 memory_limit = 128M

Tips: You need to keep memory_limit > post_max_size > upload_max_filesize

Assumption: The video file is too large, we must cut it

Use XHR2 to realize cutting and uploading files

The specific code is as follows:

var fileobj = document.getElementByTagName('input')[i].files[0];//获取文件上传对象的文件资源
const SLICESIZE = 10 * 1024 * 1024;//每次切割的大小，这里是10MB//此处可做修改
var start = 0;   //初始化截取开始位置
var end = 0;   //初始化截取终止位置
totalsize = fileobj.size; //获取文件的总的大小
while(start < totalsize){ //利用while循环将文件进行截取提交
start = end ; //
end = start + SLICESIZE; //
 
var xhr = new XMLHttpRequest(); //创建ajax对象
 
var fd = new FormData(); //创建表单对象
 
var part = fileobj.slice(start,end);//对文件进行切割，两个参数
 
fd.append(&#39;name&#39;,part);//把切割文件打包进表单对象中以便发送，其中name的值就是服务器$_FILES[&#39;name&#39;]接受处的变量名
xhr.open(&#39;POST&#39;,&#39;test.php&#39;,false);//之所以关闭异步，是为了防止文件块送达服务器的顺序出错
 
xhr.send(fd);//把打包的数据发送
}

Go to the php page and start receiving the value

At this time, the video file is transferred to upload/data/videp/demo.mov;

Next, let’s talk about this Move the file to the location you want

Because I always failed to use move_uploaded_file (you can try it), I was wondering if I could rename this temporary file.

I Try to use rename

to store the video into the database

To display it in the foreground, use

{if $brand_video}
     <embed src="http://www.ecshop.com/data/video/{$brand_video}" sutostart=true loop=true width=800 height=600></embed>
{/if}

Parameter analysis: sutostart::Whether to play automatically

Loop:: Whether to loop or not

I won’t say anything about the width and height, everyone knows it.
