php获取mp3文件信息时长修改

Jun 23, 2016 pm 01:04 PM

  function djinfo($dir)
  {
            if(!file_exists($dir)) return '';
        if(substr(php_uname('s'),0,7)=="Windows"){ //LINUX系统暂时不支持
        $player= new COM("WMPlayer.OCX");
        $media = $player->newMedia($dir);
        $time = $media->duration; //获取持续时间
        @$s_bitrate = $media->getItemInfo(Bitrate); //获取位速
        @$size=$media->getItemInfo(FileSize);//大小 
        $time = sprintf("%01.0f", $time);
        $s_duration = strftime("%H时%M分%S秒",$time-28800);
        $s_bitrate = str_replace(substr($s_bitrate,-3),"",$s_bitrate)." Kbps";
        $s_size=$this->formatsize($size);
ob_flush();flush();
           return $s_size.'|'.$s_bitrate.'|'.$s_duration;
        }else{
       return '';
        }
          }

原来的代码是这样,比如原来获取时间为 1时08分05秒  想改为 68分05秒   
各位大神如何改啊,谢谢

希望大家帮帮忙,谢谢

你是要编辑mp3文件么?从微软定义看,media应该只能读数据,不能修改mp3文件的?
https://msdn.microsoft.com/en-us/library/windows/desktop/dd563869(v=vs.85).aspx#
Bitrate和FileSize的isReadOnlyItem都是true,filesize的定义页:https://msdn.microsoft.com/en-us/library/windows/desktop/dd562991(v=vs.85).aspx

以及这个问题感觉不如直接去问vb之类的开发他们用WMPlayer.OCX能不能改文件?

我是扫描入库,不是修改MP3文件,以上的入库时间样式是  1时08分05秒   我想转换为68分05秒  

那就只是个时间显示的问题了?
$media->duration结果是秒,所以是$time/60分,$time%60秒,这样?

$time = 4085;
echo sprintf("%dmin,%02dsec", floor($time/60), $time%60);
这种感觉

$time = $time-28800;$s_duration = date('H', $time) * 60 + date('i', $time) . date("分s秒",$time);echo $s_duration;
Copy after login
68分05秒  

谢谢,搞定了!

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
