php - How to count number of the same elements in array -


I have a very simple problem. I have an array 

  $ a = array ('Dog', 'dog', 'dog', 'mouse', 'mouse', 'mouse', 'cat', 'cat');

How many counts are there are elements called 'dogs'? I tried the count () function, I know that this is not good because the count does not appear array only calculates the number of elements

for example my problem The answer will be: 

  dog = 3 mouse = 3 cat = 2

Use: 

  print_r (array_count_values ​​($ a)); Array ([dog] => 3 [mouse] => 3 [cat] => 2) $ count = array_count_values ​​($ a); Echo $ count ['dog']; // print3

I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
