php提取IMDb搜索

我需要帮助，以提取照片的网址与下面的字符串

<tr class="findResult odd">
              <td class="primary_photo"><a href="/title/tt0499549/?ref_=fn_tt_tt_1" ><img src="http://ia.media-imdb.com/images/M/MV5BMTYwOTEwNjAzMl5BMl5BanBnXkFtZTcwODc5MTUwMw@@._V1_SX32_CR0,0,32,44_AL_.jpg" /></a></td>
              <td class="result_text"><a href="/title/tt0499549/?ref_=fn_tt_tt_1" >Avatar</a> (2009) </td>
            </tr>
            <tr class="findResult even">
              <td class="primary_photo"><a href="/title/tt0417299/?ref_=fn_tt_tt_2" ><img src="http://ia.media-imdb.com/images/M/MV5BMTM3MTc3OTc0NF5BMl5BanBnXkFtZTcwOTQ0OTM1MQ@@._V1._CR34,0,295,440_SX32_CR0,0,32,44_AL_.jpg" /></a></td>
              <td class="result_text"><a href="/title/tt0417299/?ref_=fn_tt_tt_2" >Avatar: The Last Airbender</a> (2005) (TV Series) </td>
            </tr>

(2009) 
（2005）（电视连续剧）

我可以使用PHP HTML DOM解析器，但我正在学习正则表达式。这是我的密码

preg_match_all('!class="result_text"\s*>\s*<a href="/title/tt(?<imdbid>\d{7})/[^>]*>(?<title>.*?)</a>\s*(\([^\d{4}]\)\s*)?(\((?<year>\d{4})(.*?|)\)|)(?<type>[^<]*)!ims', $str, $matches);

preg\u match\u all（'！class=“result\u text”\s*>\s*\s*（\（[^\d{4}）\s*））（\（（（？\d{4}）（*？））\）（？[^考虑尝试：

preg_match_all('!<img src="(?<imageURL>[^"]*)"\s*>[.\s]*?class="result_text"\s*>\s*<a href="/title/tt(?<imdbid>\d{7})/[^>]*>(?<title>.*?)</a>\s*(\([^\d{4}]\)\s*)?(\((?<year>\d{4})(.*?|)\)|)(?<type>[^<]*)!ims', $str, $matches);

preg\u match\u all（'！[^“]*）“\s*>[.\s]*？class=“result\u text”\s*\s*（\（[^\d{4}]\）\s*））（\（（？\d{4}）（*？）））（？[^一般来说，使用正则表达式只提取一些已知格式的URL以及您信任的文件中的URL不是一个坏主意

因此，我不喜欢仅用1个正则表达式解析2个相邻标记的想法，但因为您正在学习：

<img\s[^>]*src="(?<imageURL>[^"]*)"\s*\/> # IMG tag
.*?                                       # Anything in-between IMG and A
<a\s[^>]*?href="\/title\/tt
 (?<imdbid>\d{7})                         # Got the imdbid
 \/[^>]*>(?<title>.*?)                    # Got title
 <\/a>                                    # End of A tag
 \s*\(
      (?<year>\d{4})                      # Year
 \)\s*(?:\(                               # Type is optional 
      (?<type>[^<]*)                      # Type
 \))?                                     # End of optional group

使用HTML解析器我可以使用HTML DOM解析器类，但我正在学习正则表达式：（如果你想学习正则表达式，那么就使用HTML或xml以外的文件。非常感谢你的详细解释。这也是一个很好的练习网站。
$re = "/<img\\s[^>]*src=\"(?<imageURL>[^\"]*)\"\\s*\\/> # IMG tag
.*?                                       # Anything in-between IMG and A
<a\\s[^>]*?href=\"\\/title\\/tt
