hi, i have question about php arrays. i have array like $data.
	$data=array(
array('a'='1','b'='2','c'='3','d'='4'),                                             array('a'='5','b'='6','c'='7','d'='8'),                        array('a'='9','b'='10','c'='11','d'='12')			
			);
 
i want to get only a,c,d element and create another multi dimensional array like $data1.
 
	$data1=array(
			array('a'='1','c'='3','d'='4'),
                        array('a'='5','c'='7','d'='8'),
                        array('a'='9','c'='11','d'='12')			
			);
 
 
as a next step i wanted to sort $data1 array by first value of d elements then by value of c elements and finally by a elements and get array like $data2.
	$data2=array(			
			array('a'='9','c'='11','d'='12')
			array('a'='5','c'='7','d'='8'),
			array('a'='1','c'='3','d'='4')
			);
 
i need little bit explained answer to each step. i'm stuck in here this problem. i want help..
and are there any php array function available for get $data1 array from $data easily?
