Duplicate elements array perhaps using REGEXP

[allinurl]

Hello, I have the following array where Im trying to display just one element for the first column, what I mean is not to display duplicate elements of the first column. What would be the best way to do this? Thanks

 

$array = array ( array("test foo", 10, 795, "cc"),
                 array("hello bar again", 10, 795, "dd"),
                 array("test foo", 10, 795, "cc"),
	 array("test foo", 10, 795, "cc"),
	 array("hello bar again", 10, 795, "bb"),
                 array("mike bar", 10, 775, "aa"), 
		 array("mike bar", 10, 775, "aa") );
