How do I count the number of times a value appears in an array?


This is easy with one of PHPs built-in functions. No need to write your own function to take the strain, simply use array_count_values.

Here's an example of this easy to use function so that you can see just how it works:

<?php

$values 
= array(1,1,1,2,2,2,2,3,3,4,2,5,1,3,5,3,1,5);
$most_popular array_count_values($values);
print_r($most_popular);

?>


This prints the following:

(
[1] => 5
[2] => 5
[3] => 4
[4] => 1
[5] => 3
)

So you can see it returns an array with the values of the initial array as the keys of the new array, with the number of times each value was present in the initial array as the value in the new array.
