php将HTML表格每行每列转为数组实现采集表格数据的方法

本文实例讲述了php将HTML表格每行每列转为数组实现采集表格数据的方法。分享给大家供大家参考。具体如下：

下面的php代码可以将HTML表格的每行每列转为数组，采集表格数据

    <?php
    function get_td_array($table) {
      $table = preg_replace("'<table[^>]*?>'si","",$table);
      $table = preg_replace("'<tr[^>]*?>'si","",$table);
      $table = preg_replace("'<td[^>]*?>'si","",$table);
      $table = str_replace("</tr>","{tr}",$table);
      $table = str_replace("</td>","{td}",$table);
      //去掉 HTML 标记 
      $table = preg_replace("'<[/!]*?[^<>]*?>'si","",$table);
      //去掉空白字符 
      $table = preg_replace("'([rn])[s]+'","",$table);
      $table = str_replace(" ","",$table);
      $table = str_replace(" ","",$table);
      $table = explode('{tr}', $table);
      array_pop($table);
      foreach ($table as $key=>$tr) {
        $td = explode('{td}', $tr);
        array_pop($td);
        $td_array[] = $td;
      }
      return $td_array;
    }
    ?>

希望本文所述对大家的php程序设计有所帮助。
