array_reduce ($array, own_function, $initial)Parameters:
Function takes three arguments and is described below:
Input: $array = (15, 120, 45, 78) $initial = 25 own_function() takes two parameters and concatenates them with "and" as a separator in between Output: 25 and 15 and 120 and 45 and 78 Input: $array = array (2, 4, 5); $initial = 1 own_function() takes two parameters and multiplies them. Output: 40In this program we will see how an array of integer elements is reduced to a single string value. We also passed the first element of our selection.
// PHP function to illustrate the use of array_reduce() function own_function ( $element1 , $element2 ) { return $element1 . "and" . $element2 ; } $array = array ( 15, 120, 45, 78); print_r ( array_reduce ( $array , "own_function" , "Initial" )); ?> Output:Initial and 15 and 120 and 45 and 78
In the program below, array_reduce reduces the given array to the product of all array elements using own_function().
// PHP function to illustrate the use of array_reduce() function own_function ( $element1 , $element2 ) { $element1 = $element1 * $element2 ; return $element1 ; } $array = array ( 2, 4, 5, 10, 100); print_r ( array_reduce ( $array , "own_function" , "2" )); ?> Output:80000 Link :
