Implementation of video playback and upload functions in PHP and mini-programs

Video playback and uploading functions of PHP and mini-programs

Video has become an indispensable part of Internet media content. Whether it is online classes, live broadcast platforms or film and television websites, videos play an important role. How to implement video playback and upload functions on your own website or mini-program has become a topic of concern to many developers. In this article, we will explore how to implement video playback and upload functions through PHP and small programs.

1. PHP implements video playback function

In PHP, the video playback function can be realized through the URL address of the video. The following is a simple PHP code example that shows how to implement the video playback function:

<?php
    // 获取视频的URL地址
    $videoUrl = $_GET["url"];

    // 输出视频播放器到页面
    echo "<video src='" . $videoUrl . "' controls autoplay></video>";
?>

In the above code, first obtain the URL address of the video through $_GET["url"]. Then, use the "video" tag to output the video player to the page. By setting the "src" attribute to the URL address of the video, the video can be played on the page.

2. The mini program implements the video playback function

In the mini program, you can use the "video" component to realize the video playback function. The following is a simple applet code example that shows how to implement the video playback function in the applet:

<video src="{{videoUrl}}" autoplay></video>

In the above code, the "src" attribute of the "video" tag uses the data binding of the applet Define and bind the URL address of the video to this attribute. By setting the "autoplay" attribute to autoplay, the video will automatically play after the mini program is loaded.

3. PHP implements video upload function

In PHP, you can implement the video upload function by using the "move_uploaded_file" function. The following is a simple PHP code example that shows how to implement the video upload function:

<?php
    // 上传目录
    $uploadDir = "./uploads/";

    // 上传文件
    $uploadFile = $uploadDir . basename($_FILES["video"]["name"]);
    move_uploaded_file($_FILES["video"]["tmp_name"], $uploadFile);

    // 输出上传成功的信息
    echo "视频上传成功！";
?>

In the above code, first set the upload directory to "./uploads/", that is, save the video to this directory . Then, get the name of the uploaded file through $_FILES["video"]["name"], and get the temporary path of the uploaded file through $_FILES"video". Finally, use the "move_uploaded_file" function to move the uploaded file to the specified directory.

4. Mini program implements video upload function

In the mini program, you can use the "chooseVideo" method to select a video and the "uploadFile" method to upload a video file. The following is a simple applet code example that shows how to implement the video upload function in the applet:

wx.chooseVideo({
    sourceType: ['album', 'camera'],
    success(res) {
        const tempFilePath = res.tempFilePath;

        wx.uploadFile({
            url: 'https://example.com/upload.php',
            filePath: tempFilePath,
            name: 'video',
            success(res) {
                console.log(res.data);
            }
        })
    }
})

In the above code, the "chooseVideo" method is used to select the video, which can be specified through the "sourceType" parameter The source of the video. After the selection is successful, the temporary path of the video can be obtained through "res.tempFilePath".

Then, use the "uploadFile" method to upload the video file. You need to set the "url" parameter to the address of the upload interface, the "filePath" parameter to the path of the video file, and the "name" parameter to the name of the uploaded file. After the upload is successful, the data returned by the server can be obtained through "res.data".

Summary:

Through PHP and small programs, we can easily realize the video playback and upload functions. Through the above code examples and methods, developers can quickly implement video functions in their own websites or mini programs. Hope this article is helpful to you!
