How to set array pointer to a specific position?

Is there a way to set the pointer of an array to a specific key?
I save the current position in an array using

$base_position = key($myarray);

Open in new window

I then do various reads back and forth in the array using

prev($myarray);

Open in new window

and

next($myarray);

Open in new window

at the end of the routine I want to be able to go back to my base position in the array using the key that I saved in $base_position

From Vel Eous's advice I use this code to locate he current key and then move the array pointer

/
* find out where the current type is in the array. Read through the array until $var is found*/
foreach ($aircraft_types as $key => $info):
	if (array_search($var, $info)): break; endif;
endforeach;
				
/* move the array pointer to the location of the current type */
reset($aircraft_types);
while (key($aircraft_types) !== $key && key($aircraft_types) !== null) next($aircraft_types);
