I want to set id of an element. I’m using php dom. I could not understand how following will work.

DOMElement::setIdAttribute  ( string $name  , bool $isId  )

The only description I found for this in manual is –
Declares the attribute name to be of type ID.

How can I do this ?

    If you want to add an id attribute to your html element so that it looks like <p id="frob">... you dont use setIdAttribute() – it declares that the attribute $name can be used as an unique identifier for that element – as an alternative/addition of the id attribute. Use setAttribute() like so:

    $dom = new DOMDocument();
$dom->loadHTML('<html><body><p>FROB</p></body></html>');
$dom->getElementsByTagName('p')->item(0)->setAttribute('id', 'XXX');
print $dom->saveHTML();
