Question

Okay, so I’ve got an array that has a ton of random numbers in it, like this…

$array = array(134, 12, 54, 134, 22, 22, 1, 9, 45, 45, 12, 134, 45, 134);

What I need to do, is find out what numbers are contained in my array, and if a number is duplicated in the array, I’d like to know how many times that number is found within the array. So taking the array that I listed above, I need the results to be something like this:

134: 4
12: 2
54: 1
22: 2
1: 1
9: 1
45: 3
etc.

Any bright ideas on how this might be accomplished?

Thanks!

Answer 1

See array_count_values.

<?php
print_r(array_count_values(
        array(134, 12, 54, 134, 22, 22, 1, 9, 45, 45, 12, 134, 45, 134)));

gives:

Array
(
    [134] => 4
    [12] => 2
    [54] => 1
    [22] => 2
    [1] => 1
    [9] => 1
    [45] => 3
)
