I'm having very simple issue. I have array
$a = array('dog', 'dog', 'dog', 'mouse', 'mouse','mouse', 'cat','cat');
How to count how many elements called 'dog' I have ?
I tried count() function , i know it's not good because count doesn't look into array only counts number of elements.
So for example answer for my issue would be :
dog = 3
mouse = 3
cat = 2
Use array_count_values():
print_r(array_count_values($a));
Array
(
[dog] => 3
[mouse] => 3
[cat] => 2
)
$count = array_count_values($a);
echo $count['dog']; // prints 3
you have to use array-count-values
http://www.php.net/manual/en/function.array-count-values.php
print_r(array_count_values($a));
Array
(
[dog] => 3
[mouse] => 3
[cat] => 2
)
You're looking for the array_count_values function.
$a = array('dog', 'dog', 'dog', 'mouse', 'mouse','mouse', 'cat','cat');
$counted = array_count_values($a);
$numberOfDogs = $counted['dog'];
Given your input:
$a = array('dog', 'dog', 'dog', 'mouse', 'mouse','mouse', 'cat','cat');
$var = array_count_values($a);
var_dump($var);
