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('name',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['name']接受处的变量名 xhr.open('POST','test.php',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.
