Example of Capturing Novel Website Content Function Implemented by PHP

In this paper, an example is given to describe the function of crawling novel website content realized by PHP. Share it for your reference, as follows:

Crawl free content, get mobile phones, listen to books, and do it properly.

ini_set('user_agent','Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; GreenBrowser)');
ini_set('max_execution_time', '0');
$base = 'https://www.qu.la/book/19434/';
$start = '7504808.html';
$content_grep = '/&nbsp;&nbsp;&nbsp;&nbsp;(.*)<br\/>/';
//$content_grep = '/<div id="content">(.*)<br\/>/sS';
$next_grep = '/<a id="pager_next" href=\"(\d+\.html)\" target="_top" class="next"> Under 1 Chapter <\/a>/';
$next = $start;
$file_name = ' Listen to the book .txt';
while($next) {
  echo 'getting ' . $next . PHP_EOL;
  $result = file_get_contents($base . $next);
  preg_match_all($content_grep, $result, $match);
  $isTitle = true;
  $content = "";
  foreach($match[1] as $line) {
    $line  = str_replace("<br/>", '', $line);
    $line  = str_replace(" ", '', $line);
    if($isTitle) {
      $content = $line . PHP_EOL . PHP_EOL;
      $isTitle = false;
    } else {
      $content .= '    ' . $line . PHP_EOL . PHP_EOL;
    }
  }
  $file = fopen($file_name, 'a');
  echo 'write length: ' . strlen($content) . PHP_EOL;
  fwrite($file, $content);
  fclose($file);
  echo '.';
  preg_match($next_grep, $result, $match);
  $next = $match[1];
}
