removing duplicates

[fascom746]

I have some code

<?php
 $sbq_cat=("select * from sbbleads_offer_cats where sb_ciduid=" . $sbrow_off["sb_uid"]  ); 
			//echo $sbq_cat;

		$sbrs_cat=mysql_query($sbq_cat);

		$sbcat_exists=false;
		while($sbrow_cat=mysql_fetch_array($sbrs_cat))
		{
			$catpath="";
			$cat_query=mysql_query("Select * from sbbleads_categories 
			where sb_id=".$sbrow_cat["sb_cid"] );

			while ($rs=mysql_fetch_array($cat_query))
			{
				$catpath =" > <a href=\"cat_sell.php?cid=" . $rs["sb_id"] . "\">" .$rs["sb_cat_name"]."</a>".$catpath; 
				$cat_query=mysql_query("Select * from sbbleads_categories where sb_id=" . $rs["sb_pid"] );

			}

			echo '<a href="index.php">Home</a>'.$catpath.'<br>'; 
		}
/*			if(!$sbcat_exists)
				echo $config["sb_null_char"];	//prints in case no other category than cid
*/		  ?>

The problem I am facing with this code is that it prints duplicates like

Home > Agriculture > Agriculture & By-product Agents
Home > Agriculture > Agriculture & By-product Agents
Home > Agriculture > Agriculture Product Stocks
Home > Agriculture > Agriculture & By-product Agents

I want just single line telling "Home > Agriculture > Agriculture & By-product Agents" not multiple lines. Please let me know how could I do this.
Thanks

Instead of echoing the path each time add it to an array.

Then run array_unique which will remove the duplicates and then loop through the array and print out the results
