看到很多国外网站上开始有了语音验证码功能，觉得挺好玩，而且也方便一些视力不好的人士，所以自己也尝试做了一个玩玩，是用的PHP+FLASH完成的，主要代码如下：
PHP文件  <?PHP/* vim: set expandtab tabstop=4 shiftwidth=4 foldmethod=marker: *//** * @Name voice_code.php * @Note 语音验证码 * @Author arcow@21xp.com * @Created 2007/4/26 * @Version 1.0 **/header('Content-type: audio/mpeg');//随机种子list($usec, $sec) = explode(' ', microtime());$randtime = (float) $sec + ((float) $usec * 100000);srand($randtime);//随机验证码$authnum = '';//$str = 'abcdefghijkmnpqrstuvwxyz1234567890';$str = '1234567890';$l = strlen($str);for($i=1;$i<=4;$i++){ $num=rand(0,$l); $authnum.= $str[$num];}//把随机验证码记录到session$_SESSION['auth_code'] = $authnum;//转成字符串，方便用数组调用$code = strval($authnum);readfile("sound/begin.mp3");for($i=0;$i<strlen($code);$i++){ $soundNum = $code[$i]; readfile("sound/$soundNum.mp3");}readfile("sound/end.mp3");?>Html文件 <html><head><title>语音验证码示例文件(voice verification code Sample) by arcow@21xp.com</title> <script language="javascript"> var myimages=new Array();function preloadimages() { for (i=0;i<preloadimages.arguments.length;i++) { myimages[i]=new Image(); myimages[i].src=preloadimages.arguments[i] }} preloadimages("sound/audio.jpg");</script></head><body><object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" width="0" height="0" id="code_play" align="middle"><param name="allowScriptAccess" value="always" /><param name="FlashVars" value="url=voice_code.php" /><param name="movie" value="code_play.swf"/><param name="quality" value="high" /><param name="bgcolor" value="#ffffff" /><embed id="code_play" name="code_play" src="code_play.swf" FlashVars="url=voice_code.php" quality="high" bgcolor="#ffffff" width="0" height="0" align="middle" allowScriptAccess="always" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" /></object><script language="javascript">function readVoiceCode(){ document.getElementById('code_img').src = "sound/audio.jpg"; document.getElementById('againListen').style.display=''; document.getElementById('readVoiceBtn').style.display='none'; window.document.code_play.SetVariable("isPlay", "1");}</script><a href="javascript:void(0);" onclick="javascript:readVoiceCode();" id="readVoiceBtn">读语音验证码</a><a href="javascript:void(0);" onclick="javascript:readVoiceCode();" id="againListen" style="display:none;">没听清？再听一次</a><img src='sound/default.jpg' id="code_img"></body></html>全部源码包(PHP，FLASH，声音文件等源文件)下载地址为：http://bbs.chinaunix.net/viewthread.php?tid=928953&extra=page%3D1 |
