HTML表格到PHP数组

问题描述

-------------- EDIT ------------------------

--------------EDIT------------------------

所以我要使用DOM方法.这是我到目前为止的内容:

So i am going with the DOM approach. Here is what I have so far:

  <?php function getdata(){
    $contents = file_get_contents('internatdata.htm');
    //create a DOM based off of the string from the html table
     $DOM = new DOMDocument;
   $DOM->loadHTML($contents);

   //get all tr and td
   $items = $DOM->getElementsByTagName('tr');
   $tds = $DOM->getElementsByTagName('td');

   function tdrows($elements){
       $str = "";
       for ($ii =0; $ii < $elements->length; $ii++){
            $str .= $elements->item($ii)->nodeValue . ",";


           }
          return $str;
       }

   for ($i = 0; $i < $items->length; $i++){


       echo tdrows($tds) . "; <br />";

       }

    }
?>

我遇到的问题是我只想从每个表行中选择td.我正在尝试通过嵌套循环来实现这一目标.不幸的是，它正在页面上将每个标签的文本打印多少次.我怎么能得到它，所以它只打印每个tr的td而不是dom上的每个td?

The issue I am having is that I only want to select the td's from each table row. I am trying to achieve this with a nested loop. unfortunately It is printing the text of every tag on the page how ever many times as there are tags. how can i get it so its only printing the td of each tr and not every td on the dom?

我需要使用html表作为数据源，因为我无权访问数据库.我认为能够从html表中查询数据，我需要创建一个函数以将表转换为数组或多维数组.

I need to use an html table as the source of my data because I don't have access to the database. I figure to be able to query data from the html table I need create a function to convert the table into an array, or a multidimensional array.

我有基本的想法，但我需要一些帮助来完成代码以基于html表返回数组.

I have the basic Idea I think but I need some help finishing the code to return an array based off the html table.

如果您除了将表转换为数组之外，还有其他更好的方法，请告诉我

Also If you have a better way of doing this other than converting the table to an array then please let me know

这是我到目前为止的想法:

Here is the idea I had so far:

 <?php
 function getdata(){

    $contents = file_get_contents('data.htm');
    //add delimiters (semicolon for a row and comma for a cell) ???

    $stripped = strip_tags($contents);

    //explode into an array based off the delimiters above ???


    }
    ?>

推荐答案

我已经更新了您的修改以进行修复.

I've updated your edit to fix it.

function tdrows($elements)
{
    $str = "";
    foreach ($elements as $element) {
        $str .= $element->nodeValue . ", ";
    }

    return $str;
}

function getdata()
{
    $contents = "<table><tr><td>Row 1 Column 1</td><td>Row 1 Column 2</td></tr><tr><td>Row 2 Column 1</td><td>Row 2 Column 2</td></tr></table>";
    $DOM = new DOMDocument;
    $DOM->loadHTML($contents);

    $items = $DOM->getElementsByTagName('tr');

    foreach ($items as $node) {
        echo tdrows($node->childNodes) . "<br />";
    }
}

getdata();
