How can I get td values using dom and php - php

Question

I have a table such this :
<table>
<tr>
<td>Values</td>
<td>5000</td>
<td>6000</td>
</tr>
</table>
And I want to get td's content. But I could not manage it.
<?PHP
$dom = new DOMDocument();
$dom->loadHTML("figures.html");
$table = $dom->getElementsByTagName('table');
$tds=$table->getElementsByTagName('td');
foreach ($tds as $t){
echo $t->nodeValue, "\n";
}
?>

Answer 1

There are multiple problems with this code:
To load from an HTML file, you need to use DOMDocument::loadHTMLFile(), not loadHTML() as you have done. Use $dom->loadHTMLFile("figures.html").
You can't use getElementsByTagName() on a DOMNodeList as you have done (on $table). It can only be used on a DOMDocument.
You could do something like this:
$dom = new DOMDocument();
$dom->loadHTMLFile("figures.html");
$tables = $dom->getElementsByTagName('table');
// Find the correct <table> element you want, and store it in $table
// ...
// Assume you want the first table
$table = $tables->item(0);
foreach ($table->childNodes as $td) {
if ($td->nodeName == 'td') {
echo $td->nodeValue, "\n";
}
}
Alternatively, you could just directly search for all elements with tag name td (though I'm sure you want to do that in a table-specific manner.

You should use a for loop to display the multiple td's with id attributes in it such that each td must signify a different id in html file
for example
for($i=1;$i<=10;$i++){
echo "<td id ='id_".$i."'>".$tdvalue."</td>";
}
and then again you can fetch the td values by just iterating another for loop over getElementById

The td data can be found inside childNodes
$dom = new domDocument;
$dom->loadHTML("your-url");
$tables = $dom->getElementsByTagName('table');
$rows = $tables->getElementsByTagName('tr');
foreach ($rows as $row) {
echo $row->childNodes[0]->nodeValue;
}
