1. PHP recursive function to realize number accumulation Example: Copy code Code example:2. PHP recursive function cumulative summation php Example of array recursive summation: convert an array, or a two-dimensional array of multiple numbers and return the sum of all values. Example: Copy code Code example:
/*** a flat array ***/ $array = array(10, 20, 5, 34, 129); /*** add the values ***/
echo arraySumRecursive($array)." /*** a multi dimensional array ***/ $array = array(10, 20, 5, array(5, 2, 3, array(5, 3, array(2, 10, array(19, 1) ),3 ), 2, 7 ), 3 ); /*** add the values ***/ echo arraySumRecursive($array); ?> |
