Tips on operating files in php

This article mainly introduces the related skills of php file operation. Interested friends can refer to it. I hope it will be helpful to everyone.

The details are as follows:

For example, remove the first few lines in the lrc file:

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

php implementation code is as follows:

<?php
foreach (new DirectoryIterator(&#39;./&#39;) as $fileInfo) {
  if($fileInfo->isDot()) continue;
  if($fileInfo->getExtension()=="lrc"){
    $handle = fopen($fileInfo->getFilename(), &#39;rw&#39;);
    $line_num=0;
    while(!feof($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(&#39;done&#39;);
        break;
      }
