I want to replace a string such as:
<input type="hidden" name="id" value="12345" />
but the problem I have is that the value's value (12345) is different everytime so how can I do what I'm trying to do? ..I'm guessing regex' but haven't a clue.

The
s pattern modifier is pointless when there are no dots in the pattern.Reliably and intuitively target and destroy the first occurring HTML input element with the qualifying name attribute using DomDocument and XPath.
Code: (Demo)
$html = <<<HTML
<form>
<input type="hidden" name="id" value="12345" />
</form>
HTML;
$dom = new DOMDocument();
$dom->loadHTML($html, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
$input = (new DOMXPath($dom))
->query('//input[@name="id"]')
->item(0);
$input->parentNode->removeChild($input);
echo $dom->saveHTML();
Output:
<form>
</form>
