Dynamic meta Description, meta Keywords and Title using PHP

Changing your the meta description, meta keywords and title of a php page.This is a follow up of a post that I had posted here a few weeks back.

I only make some changes to the header.php file and the header.php file will handle the value of $section and change the title, the meta description and meta keywords of the webpage.

<?
	//Conditional Statement to change the title, meta description and meta keywords.
	if ($section == "home"){
		$title = "Unique title for home page";
		$description = "A Unique description for 'Home' Section";
		$keyword = "Home";
	}else if ($section == "profile"){
		$title = "Special title for profile page";
		$description = "A Special description for 'Profile' Section";
		$keyword = "Profile";
	}else if ($section == "product"){
		//Another Conditional Statement to change the title, meta description and meta keywords base on the productID.
		$productID = $_REQUEST["productID"];
		if($productID == "x"){
			$title = "Product page for X";
			$description = "A description for 'Product X'";
			$keyword = "Product X";
		}else if($productID == "y"){
			$title = "Product page for Y";
			$description = "A description for 'Product Y'";
			$keyword = "Product Y";
		}else if($productID == "z"){
			$title = "Product page for Z";
			$description = "A description for 'Product Z'";
			$keyword = "Product Z";
		}else{
			$title = "A title for product page";
			$description = "A description for 'Product' Section";
			$keyword = "Product X, Product Y, Product Z";
		}
	}else if ($section == "contact"){
		$title = "Contact me now";
		$description = "Form for contact me";
		$keyword = "Conact me, form";
	}
	//Write the title, meta description and meta keywords into a header html tag
	echo "<header>";
	echo "<title>".$title."</title>";
	echo "<meta name='description' content='".$description."'>";
	echo "<meta name='keywords' content='".$keyword."' />"; 
	echo "</header>";
	//Create a table and base on the value os $section, toggle the state of the selected button.
	echo "<table cellpadding='0' cellspacing='0' border='0' width='100%' ><tr>";
	//If $section == home, make the text 'Home' unclickable else makt it into a clickable hyperlink
	if ($section != "home"){
		echo "<td align='center'><a href='home.php'>Home</a></td>";
	}else{
		echo "<td align='center'><b>Home</b></td>";
	}
	//If $section == profile, make the text 'Profile' unclickable else makt it into a clickable hyperlink
	if ($section != "profile"){
		echo "<td align='center'><a href='profile.php'>Profile</a></td>";
	}else{
		echo "<td align='center'><b>Profile</b></td>";
	}
	//If $section == product, make the text 'Product' unclickable else makt it into a clickable hyperlink
	if ($section != "product"){
		echo "<td align='center'><a href='product.php'>Product</a></td>";
	}else{
		echo "<td align='center'><b>Product</b></td>";
	}
	//If $section == contact, make the text 'Contact Us' unclickable else makt it into a clickable hyperlink
	if ($section != "contact"){
		echo "<td align='center'><a href='contact.php'>Contact Us</a></td>";
	}else{
		echo "<td align='center'><b>Contact Us</b></td>";
	}
	echo "</tr></table>";
	echo "<br>";
?>
