I don't understand why the code is not working?

Question

PHP

Getting the contents of the head tag using code

<?
$html = file_get_html('http://site.ru/');
foreach ($html->find("head") as $elements) {
    $head = $elements;
}
echo $head;
?>

the code obtained with this does not display some elements, but if you manually copy the contents of the head tag from the site that I'm parsing and paste into my site, then everything works. Why is this happening? I checked that the resulting code using the parser is absolutely identical to the source code of the site that I am parsing.

Answer 1

Because you're redefining $head every time, you need to add a dot before "equals". So with each iteration, you will add new data to the end

<?
$html = file_get_html('http://site.ru/');
foreach ($html->find("head") as $elements) {
    $head .= $elements;
}
echo $head;
?>
