将HTML表格的每行每列转为数组，采集表格数据

<? 
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); 
//PHP开源代码

        $table = str_replace("</td>","{td}",$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; 
}
