I need a part of code html by a file from file_get_contents(url)
I do
$variableee = file_get_contents("http://url.com/path/to/file");
echo $variableee;
Ok now in Variableee I've all the url's code.
In this code there is a part that I need. I need a table with class name "table".
Es.
<div>text</div>
<span> text </span>
<table class="table">
<tr><td>Text that I need</td></tr>
</table>
How I can get it?
Sorry for bad english.

If you want the data within PHP itself use the built-in DOM parser,
<?php
$doc = new DOMDocument();
$doc->loadHTML($variableee);
$arr = $doc->getElementsByTagName("table"); // DOMNodeList Object
foreach($arr as $item) { // DOMElement Object
echo $item->nodeValue;
}
?>
EDIT: Parse using the class name with DOMXPath
$doc = new DOMDocument();
$doc->loadHTML($variableee);
$classname = 'table';
$a = new DOMXPath($doc);
$spans = $a->query("//*[contains(concat(' ', normalize-space(#class), ' '), ' $classname ')]");
foreach($spans as $item) { // DOMElement Object
echo $item->nodeValue;
}
