How to grab BT Paradise movie data

I had a rest at night and wanted to watch two good movies.

I searched for a long time but couldn’t find what I wanted to watch.

I suddenly thought that someone had crawled Zhihu’s user data before. I had a whim,

It’s okay to crawl down the movie information of BT Paradise,I can check the database directly next time.

I can only say that I am so bored , haha, I can still code ^_^

1. Grab the website html source code

<span style="font-size:24px;">$url = "www.bttiantang.cc";
$html = shell_exec("curl $url");</span>

2. Get the total number of pages, Total number of movies (regular matching)

<span style="font-size:24px;">preg_match("/<span class=\"pageinfo\">.*?<\/span>/", $html, $pageCount);
preg_match_all("/\d{1,10000}/",$pageCount[0],$pageCount);</span>

3. Capture movie information (regular matching information)

<span style="font-size:24px;">preg_match("/\d{4}\/\d{2}\/\d{2}/" , $pageInfo[0][$i], $updateTime);

preg_match("/<font color=\"#FF6600\">(.*?)<i>/" , $pageInfo[0][$i], $movieName);
        
preg_match("/<strong>(\d{1})<\/strong>/" , $pageInfo[0][$i], $movieScore_int);
     
preg_match("/<em class=\"fm\">(\d{1})<\/em>/" , $pageInfo[0][$i], $movieScore_decimal);
        
preg_match("/href=\"(.*?)\"/" , $pageInfo[0][$i], $movieUrl);
      
preg_match("/<p class=\"des\">(.*?)<\/p>/" , $pageInfo[0][$i], $actor);
       </span>

4. Insert into the database and you’re done

Generally speaking, the speed of php crawling is quite fast. It takes less than 4 minutes to collect more than 20,000 pieces of information.

<?php

preg_match("/<span class=\"pageinfo\">.*?<\/span>/", $html, $pageCount);

$pageSize = intval($pageCount[0][0]);
$movieCount = $pageCount[0][1];

$conn = mysql_connect('***','***','');
mysql_select_db('***',$conn);
mysql_query('set names utf8',$conn);

for($j=1;$j<=$pageSize;$j++){
    $movieHtml = shell_exec("curl $url?PageNo=$j");
    preg_match_all("/<div class=\"item cl\">.*?<\/div>/s", $movieHtml, $pageInfo);
    for($i=0;$i<count($pageInfo[0]);$i++){
        preg_match("/\d{4}\/\d{2}\/\d{2}/" , $pageInfo[0][$i], $updateTime);
        /******clear ad*****/
            if(empty($updateTime))continue;
        /*******************/
        $updateTime = str_replace('/','-',$updateTime[0]);


        preg_match("/<font color=\"#FF6600\">(.*?)<i>/" , $pageInfo[0][$i], $movieName);
        /*****same conditions*****/
        if(empty($movieName))
            preg_match("/<b>(.*?)<i>/" , $pageInfo[0][$i], $movieName);

        preg_match("/<strong>(\d{1})<\/strong>/" , $pageInfo[0][$i], $movieScore_int);
        $movieScore_int = $movieScore_int[1];
        preg_match("/<em class=\"fm\">(\d{1})<\/em>/" , $pageInfo[0][$i], $movieScore_decimal);
        $movieScore_decimal = $movieScore_decimal[1];
        $movieScore = floatval($movieScore_int.'.'.$movieScore_decimal);

        preg_match("/href=\"(.*?)\"/" , $pageInfo[0][$i], $movieUrl);
        $movieUrl = $movieUrl[1];

        preg_match("/<p class=\"des\">(.*?)<\/p>/" , $pageInfo[0][$i], $actor);
        $movieActor = str_replace("<em>",'',str_replace("</em>",'',$actor[1]));

        mysql_unbuffered_query("insert into movie (name,actor,url,update_ts,score) values ('$movieName','$movieActor','$movieUrl',<span style="white-space:pre">	</span>'$updateTime','$movieScore')");
    }
