extract duplicates and how many times they occur in php array - php

Question

I am developing a user driven eCommerce website and need some help. What I have is a function that will loop through an array remove duplicates and how many times they occur. I then need to run a function on each of those extracted duplicates as many times as they occur. The code I have so far works, but breaks when there are multiple duplicates with the same repetition count. Here is the code I have made so far..
$affiliates = array(11,11,12,12,13,13,13,14,14,14,14); //breaks the code
$affiliates = array(11,11,13,13,13,14,14,14,14,12,12,12,12,12); // works fine
$array = array();
$match_count = array();
foreach($affiliates as $key => $affiliate) {
$array[] = $affiliate;
}
arsort($array); // keeps array index in order
foreach($array as $arrays) {
if(array_value_count($arrays,$array) > 1) {
$match_count[] = array_value_count($arrays,$array);
}
}
$match_count = array_unique($match_count);
$array_unique = arrayDuplicate($array);
$final_array = array_combine($match_count,$array_unique);
foreach($final_array as $key => $value) {
for($i = 0; $i < $key; $i++) {
echo 'addOrder(affiliate_id = ' . $value . ') . '<br>';
}
}
the functions
function unique_array($array) {
return array_unique($array, SORT_NUMERIC);
}
function arrayDuplicate($array) {
return array_unique(array_diff_assoc($array,array_unique($array)));
}
function array_value_count($match, $array) {
$count = 0;
foreach ($array as $key => $value)
{
if ($value == $match)
{
$count++;
}
}
return $count;
}
to fix the duplicates breaking the code I have tried this
if(count($array_unique) - count($match_count_unique) == 1 ) // do something
or
if(count($array_unique) != count($match_count_unique) == 1 ) // do something
How would I know where to add the missing duplicate value count and array items correctly without them getting out of sync? OR Is there a better way of doing this?

Answer 1

Taken from How do I count occurrence of duplicate items in array
$array = array(12,43,66,21,56,43,43,78,78,100,43,43,43,21);
$vals = array_count_values($array);
echo 'No. of NON Duplicate Items: '.count($vals).'<br><br>';
print_r($vals);
Result
No. of NON Duplicate Items: 7
Array
(
[12] => 1
[43] => 6
[66] => 1
[21] => 2
[56] => 1
[78] => 2
[100] => 1
)
Duplicate items = (Array Size) - (Total Number of Unique Values)

<?php
$affiliates = array(11,11,12,12,13,13,13,14,14,14,14);
// get an array whose keys are the aff# and
//the values are how many times they occur
$dupes = array();
foreach ($affiliates as $aff) {
$dupes[$aff]++;
}
// remove the 1's since those aren't dupes
$dupes = preg_grep('~^1$~',$dupes,PREG_GREP_INVERT);
// de-dupe the original array
$affiliates = array_unique($affiliates);
// for each duped affiliate...
foreach ($dupes as $aff => $affCount) {
// for each time it was duped..
for ($c=0;$c<$affCount;$c++) {
// do something. $aff is the aff# like 11
}
}
?>
