How to Implement Video Upload with PHP

Implementing PHP video upload may be challenging for beginners, but this article helps you master the necessary knowledge.

Videos are essentially files, and their handling principles are the same as other file uploads.

Below is a concrete code example that details the method for uploading videos using PHP.

First, the front‑end HTML form code is as follows:

<code>&lt;html&gt;
&lt;head&gt;
    &lt;meta http-equiv="Content-Type" content="text/html; charset=gb2312"&gt;
    &lt;title&gt;PHP中文网上传视频&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
&lt;form action='demo42.php' method=post enctype="multipart/form-data"&gt;
    &lt;input type="hidden" name="MAX_FILE_SIZE" value="2000000000"&gt;
    &lt;input type=file name=upfile size=20&gt;
    &lt;input type=submit value='上传文件'&gt;
&lt;/form&gt;
&lt;/body&gt;
&lt;/html&gt;</code>

Front‑end page effect:

Back‑end PHP code for handling the video upload:

<code>&lt;?php
/**
 * PHP上传视频
 */
$upfile = $_FILES['upfile'];

function upload_file($files, $path = "./upload", $imagesExt = ['jpg','png','jpeg','gif','mp4'])
{
    // 判断错误号
    if (@$files['error'] == 00) {
        // 判断文件类型
        $ext = strtolower(pathinfo(@$files['name'],PATHINFO_EXTENSION));
        if (!in_array($ext,$imagesExt)){
            return "非法文件类型";
        }
        // 判断是否存在上传到的目录
        if (!is_dir($path)){
            mkdir($path,0777,true);
        }
        // 生成唯一的文件名
        $fileName = md5(uniqid(microtime(true),true)).'.'.$ext;
        // 将文件名拼接到指定的目录下
        $destName = $path."/".$fileName;
        // 进行文件移动
        if (!move_uploaded_file($files['tmp_name'],$destName)){
            return "文件上传失败！";
        }
        return "文件上传成功！";
    } else {
        // 根据错误号返回提示信息
        switch (@$files['error']) {
            case 1:
                echo "上传的文件超过了 php.ini 中 upload_max_filesize 选项限制的值";
                break;
            case 2:
                echo "上传文件的大小超过了 HTML 表单中 MAX_FILE_SIZE 选项指定的值";
                break;
            case 3:
                echo "文件只有部分被上传";
                break;
            case 4:
                echo "没有文件被上传";
                break;
            case 6:
            case 7:
                echo "系统错误";
                break;
        }
    }
}
echo upload_file($upfile);
?&gt;</code>

The upload_file function not only supports video uploads but also image uploads, and each step is thoroughly commented for easy learning.

Testing the upload with a video yields the following results:
