Getting back to those that helped. I ende up splitting the arrays one
for start and one for end. I then added 0 to start and subtracted the
last from start. here is the code I ended up with:
$a=array();
while($d=mysql_fetch_array($start_angle_query))
{
$a[]=$d[0];
}
//copies mysql_fetch_array into an array
$b=array();
$b =$a; // make two arrays one for start of angle 2nd for end of angle
$degree_adjuster=360/array_sum($b); //constant for circle
array_unshift($a,0 ); // add 0 for start angle
$start_angle=array(); // new array to hold values for start vector
$end_angle=array(); //new array to hold values for end vector
array_pop($a); //trim one array for start so numbers don't end on 360
while($a) //iterate till array is empty
{
array_push($start_angle,(end($start_angle)+ $a[0]));
/*enter numbers in array $start_angle adding the last number in array
and adding the
first number from modified original array*/
array_shift($a);//delete first value of array
}
while($b)
{
array_push($end_angle,(end($end_angle)+$b[0]));
array_shift($b);
}
