how to print cells of a table with simple html dom
提问by Andres SK
i have this html code. Im using Simple HTML Dom to parse the data into my own php script.
我有这个 html 代码。我使用 Simple HTML Dom 将数据解析为我自己的 php 脚本。
<table>
<tr>
<td class="header">Name</td>
<td class="header">City</td>
</tr>
<tr>
<td class="text">Greg House</td>
<td class="text">Century City</td>
</tr>
<tr>
<td class="text">Dexter Morgan</td>
<td class="text">Miami</td>
</tr>
</table>
I need to get the text inside the TDs in an array, example:
我需要在数组中获取 TD 中的文本，例如：
$array[0] = array('Greg House','Century City'); $array[1] = array('Dexter Morgan','Miami');
$array[0] = array('Greg House','Century City'); $array[1] = array('德克斯特摩根','迈阿密');
I've tried several ways to get that but i've fail in each and everyone of them. Can someone give me a hand?
我尝试了几种方法来获得它，但我在每个方法中都失败了。有人可以帮我一把吗？

This should do:
这应该做：
// get the table. Maybe there's just one, in which case just 'table' will do
$table = $html->find('#theTable');
// initialize empty array to store the data array from each row
$theData = array();
// loop over rows
foreach($table->find('tr') as $row) {
// initialize array to store the cell data from each row
$rowData = array();
foreach($row->find('td.text') as $cell) {
// push the cell's text to the array
$rowData[] = $cell->innertext;
}
// push the row's data array to the 'big' array
$theData[] = $rowData;
}
print_r($theData);

It will work.. try this
它会工作..试试这个
include('simple_html_dom.php');
$html = file_get_html('mytable.html');
foreach($html->find('table tr td') as $e){
$arr[] = trim($e->innertext);
}
print_r($arr);
You can get data from any html tag even attributes too...
您也可以从任何 html 标签甚至属性中获取数据...

You should do this so:
你应该这样做：
// initialize empty array to store the data array from each row
$theData = array();
// loop over rows
foreach($html->find('#theTable tr') as $row) {
// initialize array to store the cell data from each row
$rowData = array();
foreach($row->find('td.text') as $cell) {
// push the cell's text to the array
$rowData[] = $cell->innertext;
}
// push the row's data array to the 'big' array
$theData[] = $rowData;
}
print_r($theData);
