Loop throw array, detect max value, and reset prev one - php

Question

I would like someone to help me with this one, please.
I have this array.
foreach ($callersHistoryArray as $key => $value) {
//check for duplicates and find the highest call duration
if(in_array($value['caller'], $item, true) && $value['process'] == 0)
{
$duplicates = array(
'key' => $key,
'totalTime' => $callersHistoryArray[$key]['totalDurationTime']
);
echo print_r($duplicates, true);
if ($duplicates['totalTime'] > $max) {
$max = $duplicates['totalTime'];
$value['unique'] = 1;
}
}
I loop throw $callersHistoryArray and detect duplicates, create a new array and find the max totalTime from them and set unique value to 1.
When I go to second position in the foreach-loop, the previous one must change unique to 1. But I can't do that. I used prev($callersHistoryArray), to get last one but nothing.

I don't fully understand the question. I suspect you want to start with something like this:
<?php
$duplicates = array();
$maxTime = 0;
$unique = null;
foreach ($callersHistoryArray as $key => $value) {
//check for duplicates and find the highest call duration
if(in_array($value['caller'], $item, true) && $value['process'] == 0)
{
if ($maxTime < $value['totalDurationTime']) {
$maxTime = $value['totalDurationTime'];
$unique = $key;
}
$duplicates[] = $value;
}
}
echo print_r($duplicates, true); // array of duplicates
echo print_r($callersHistoryArray[$unique], true); // item with highest time
Bugs notwithstanding, that should give you an array of the duplicates, and also tell you which item has the maximum duration. I don't know where $item comes from, so YMMV.
You might also need to handle two items having the same max duration.
