Array sort by counting elements with the same value

[fabiuz]

Hi,

I need to sort an array by count how many times each value is present in the array and then sort the array starting from the value that has majority.

es.

array('yellow','red','brown','red','yellow','red')

I want to sort and "clean" it (array_unique) and get this result:

1th red, 2nd yellow, 3th brown ...

How can I do?

thanks a lot!

// Define the array
$colors = array('yellow','red','brown','red','yellow','red');

// Count the unique values
$color_count = array_count_values($colors);

// Do a reverse sort to put them in order of the one with the most to the one with the least
arsort($color_count);

// Output using print_r
print_r($color_count);

/* Output:  Array ( [red] => 3 [yellow] => 2 [brown] => 1 ) */


// You can also flip the keys and values if you so desire:
$color_count_flip = array_flip($color_count);
print_r($color_count_flip);

/* Output:  Array ( [3] => red [2] => yellow [1] => brown )  */

Thanks a lot!

At the end I have found that php function too, I was missing it in the array function list when I have searched the first time.

I have solved my issue with two code rows:

//order the values in the way  I need
$my_new_array = array_count_values($my_array);

//creates a new array using previos keys like values and assigning it news numeric keys:

$my_new_array = array_keys($my_new_array);

Thanks again!
