本文实例讲述了php去掉文件前几行的方法。分享给大家供大家参考。具体如下:

比如去掉lrc文件中开头几行:

[ti:]
[ar:]
[al:]
[by:cww.99Lrc.net]
[00:00.59]dasfdasfasdf
[00:30.18]dafadsf

php实现代码如下:

<&#63;php
foreach (new DirectoryIterator('./') as $fileInfo) {
  if($fileInfo->isDot()) continue;
  if($fileInfo->getExtension()=="lrc"){
    $handle = fopen($fileInfo->getFilename(), 'rw');
    $line_num=0;
    while(!feof($handle)){
      $str=fgets($handle, 1024);
      if(strstr($str, "www.99Lrc.net")){
        ob_start();
        fpassthru($handle);
        //fclose($handle);
        file_put_contents($fileInfo->getFilename(),ob_get_clean());
        printf('done');
        break;
      }
      $line_num++;
    }
    fclose($handle);
    echo $fileInfo->getFilename() . PHP_EOL;
  }
}

Copy after login

希望本文所述对大家的php程序设计有所帮助。
