Embedding and controlling Flash animation using PHP and SWFObject

With the development of the Internet, Flash animation has gradually become an indispensable part of network interface design. However, in order to make Flash animations display and run normally on web pages, we need to use relevant tools and technologies. This article will introduce how to embed and control Flash animation through PHP and SWFObject.

1. Introduction to SWFObject

SWFObject is a JavaScript library used to embed Flash animations and provide some basic control functions. It has good cross-browser compatibility and provides multiple ways to embed Flash, allowing users to choose different ways according to their needs.

2. PHP and SWFObject implement Flash animation embedding

First, we need to create a Flash animation file, for example named "demo.swf". Then, in our PHP code, use the embed SWFObject library:

<?php
    include('path/to/swfobject.js');
?>

Next, create an HTML container to embed our Flash animation:

<div id="flashContent">
    <p>如果您看到这个页面，意味着您没有安装Flash插件，或者您的浏览器不支持Flash。</p>
</div>

In this container, we can use JavaScript Call the related functions of SWFObject and embed our Flash animation into it:

<script type="text/javascript">
    swfobject.embedSWF("demo.swf", "flashContent", "300", "200", "9.0.0");
</script>

In this code, "demo.swf" is the Flash animation file we want to embed, and "flashContent" is the file we want to embed in the HTML container The ID of the div tag created in . The next two parameters are the width and height of the Flash animation. The last parameter specifies the minimum version number of Flash to ensure that the Flash plug-in version used is high enough.

3. PHP and SWFObject realize Flash animation control

In addition to embedding Flash animation, SWFObject also provides some basic control functions. For example, we can use SWFObject's "getObjectById" function in JavaScript to obtain the Flash animation object and control its events and properties.

For example, we can implement a simple button through the following code. After clicking the button, the Flash animation will pause or continue playing:

<script type="text/javascript">
    var isPlaying = true;
    var flashMovie = swfobject.getObjectById("flashContent");

    function togglePlay() {
        if (isPlaying) {
            flashMovie.stop();
            isPlaying = false;
        } else {
            flashMovie.play();
            isPlaying = true;
        }
    }
</script>

<button onclick="togglePlay()">暂停/播放</button>

In this code, the "flashMovie" variable saves The obtained Flash animation object. In the "togglePlay" function, we check whether the current Flash animation is playing. If so, we call the "stop" function to pause playback and set the "isPlaying" variable to false; if not, we call the "play" function to continue playing and set the "isPlaying" variable to true. Finally, we bind this function to a button so that users can easily control the playback of Flash animations.

4. Summary

In this article, we introduced how to use PHP and SWFObject to implement Flash animation embedding and control. Through these simple code examples, we can create richer and more interactive Flash animation web pages, improving user experience and page attractiveness. At the same time, we should also pay attention to controlling the size and loading speed of Flash animations to better adapt to user needs.
