PHP计算数组中值的和与乘积的方法(array_sum与array_product函数),sumproduct
本文实例讲述了PHP计算数组中值的和与乘积的方法。分享给大家供大家参考,具体如下:
一、概述:
array_sum() 函数用于计算数组中所有值的和。
array_product() 函数用于计算数组中所有值的乘积。
二、使用示例:
array_sum()
PHP array_sum() 函数用于计算数组中所有值的和,以整数或浮点数返回计算结果,非数字的单元将视作 0 。
语法:
number array_sum( array array )
例子:
<?php $arr_a = array(1, 2, 3, "a"); echo array_sum($arr_a); //输出:6 ?>
array_product()
PHP array_product() 函数用于计算数组中所有值的乘积,以整数或浮点数返回计算结果,非数字的单元将视作 0 。
语法:
number array_product( array array )
例子:
<?php $arr_a = array(1, 2, 3); echo array_product($arr_a); //输出:6 $arr_b = array(1, 2, 3, "abc"); echo array_product($arr_b); //输出:0 ?>
