How to play video files with subtitles using PHP?
With the development of Internet technology, video has become one of the most popular forms of online content. Now, many video files are equipped with subtitles, which makes it easier for users to understand and digest video content. So, how to use PHP to play video files with subtitles on a web page? This article will introduce it to you in detail.
First of all, we need to prepare the following environment:
- A server with a PHP running environment (such as Apache or Nginx);
- A video file (supports common video format, such as MP4);
- related subtitle files (such as SRT format).
Next, we will guide you step by step on how to use PHP to implement this function.
Step one: Create a simple web page
Build a simple web page on your server, which can be written in HTML. For example, create a file called "index.php" and add the following content in the file:
1 2 3 4 5 6 7 8 9 10 11 12 |
|
In this example, we use the <video> tag to embed the video , where the src attribute specifies the path of the video file, and the type attribute specifies the type of the video file. At the same time, we use the <track> tag to embed the subtitle file, where the src attribute specifies the path to the subtitle file, and the kind attribute specifies the type of subtitle. The srclang attribute specifies the language of the subtitles, and the label attribute specifies the label for the subtitles.
Step 2: Add PHP code to control the display of subtitles
Now, we need to write PHP code to control the display of subtitles. Create a file named "subtitles.php", and then add the following code to the file:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
|
The function of this code is to read the content of the subtitle file and format each subtitle in a certain format output.
Step 3: Combine the subtitles with the video
The last step is to combine the video with the subtitles. Modify the "index.php" file and replace the letters <track> tags with the following PHP code:
1 |
|
The function of this code is to pass include The statement embeds the code in the "subtitles.php" file written previously into the web page.
At this point, we have completed all code writing. Now, you only need to place the video file (video.mp4), subtitles file (subtitles.srt), and the two PHP files (index.php and subtitles.php) created previously in the corresponding directory on the server. Then, the video file with subtitles can be played in the web page by accessing the index.php file.
Summary:
This article introduces how to use PHP to play video files with subtitles on web pages. Through the combination of simple HTML and PHP code, we can realize the function of reading subtitle files and combining subtitles with videos. This provides users with a better viewing experience and provides more interactivity.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
