矩阵中偶数和奇数频率的php程序

给定一个 m*n 阶矩阵，那么任务是找到矩阵中偶数和奇数的频率
例子：

Input : m = 3, n = 3
        { 1, 2, 3 }, 
        { 4, 5, 6 }, 
        { 7, 8, 9 }
Output : Frequency of odd number =  5 
         Frequency of even number = 4


Input :   m = 3, n = 3
         { 10, 11, 12 },
         { 13, 14, 15 },
         { 16, 17, 18 }
Output : Frequency of odd number  =  4 
         Frequency of even number  = 5

PHP

输出：

Frequency of odd number = 5  
 Frequency of even number = 4
