Dynamic HTML Creation

Is it possible to use the DOM to add (HTML) elements to a page at the time the page is being shown? The HTML and VBScript shown below is a simplified version of what I need to do but of course I need to do it in PHP. Since PHP is server-side (right?) perhaps it is not possible. <HTML> <HEAD> <Title>Dynamic Table Demo</Title> </HEAD> <Script Language=VBScript> Sub Window_Onload Set NewRow = document.createElement("TR") Set NewCell = document.createElement("TD") NewCell.innerText = "Cell Text" NewRow.appendChild NewCell TableBody.appendChild NewRow End Sub </Script> <Body> <h1>Dynamic Table Demo</h1> <Table Id=NewTable Cols=1 border=1 Width=50%> <TBody Id=TableBody> </TBody> </Table> </Body> </HTML>
