Implementing cost in time calculations. How? - php

Question

I have the following function that adds the times contained in an array. It doesn't return the pay out. I would like to return the totalTime AND the totalPayOut.
Like so:
function sumTimesInArray($times = []) {
$seconds = 0;
foreach ($times as $time) {
list($hour, $minute, $second) = explode(":", $time);
$seconds += $hour * 3600;
$seconds += $minute * 60;
$seconds += $second;
}
$hours = floor($seconds / 3600);
$seconds -= $hours * 3600;
$minutes = floor($seconds / 60);
$seconds -= $minutes * 60;
return sprintf("%02d:%02d:%02d", $hours, $minutes, $seconds);
}
$times = ["01:00:00","00:15:00","00:00:30",]; // = 01:15:30 hours
$pay = 10;
$totalTime = sumTimesInArray($times);
print($totalTime);
Given a pay of $10/hour, how would I implement this so that it includes the prorated pay for fractional hours? Currently working on it.

this is the code i have tried, you can try
Syntax PHP
<?php
function sumTimesInArray($pay, $times) {
$dataPayouts = array();
$payoutTotal = 0;
$totalSeconds = 0; // not reset
foreach ($times as $time) {
list($hour, $minute, $second) = explode(":", $time);
$seconds = 0; // reset
$seconds += $hour * 3600;
$seconds += $minute * 60;
$seconds += $second;
$totalSeconds += $seconds;
$itemPayout = ($pay / 3600) * $seconds;
$dataPayouts[] = array(
'time' => $time,
'pay_per_hour' => $pay,
'item_payout' => $itemPayout
);
$payoutTotal += $itemPayout;
}
$hours = floor($seconds / 3600);
$seconds -= $hours * 3600;
$minutes = floor($seconds / 60);
$seconds -= $minutes * 60;
$resume = array(
'hour_total' => gmdate("H:i:s", $totalSeconds),
'payout_total' => $payoutTotal,
'details' => $dataPayouts
);
return $resume;
}
$times = array("01:00:00","00:15:00","00:00:30",); // = 01:15:30 hours
$pay = 10;
echo json_encode(sumTimesInArray($pay, $times));
Result JSON
{
"hour_total": "01:15:30",
"payout_total": 12.583333333333,
"details": [
{
"time": "01:00:00",
"pay_per_hour": 10,
"item_payout": 10
},
{
"time": "00:15:00",
"pay_per_hour": 10,
"item_payout": 2.5
},
{
"time": "00:00:30",
"pay_per_hour": 10,
"item_payout": 0.083333333333333
}
]
}

You should have a look at the DateTime and DateIntervall class (Doc). It can sum times and parse them for you, so you do not have to do it yourself.
But you can also easy modify your code:
function sumTimesAndCalcPay($times = [], $payPerHour = 1) {
$seconds = 0;
foreach ($times as $time) {
list($hour, $minute, $second) = explode(":", $time);
$seconds += $hour * 3600;
$seconds += $minute * 60;
$seconds += $second;
}
$hours = floor($seconds / 3600);
$seconds -= $hours * 3600;
$minutes = floor($seconds / 60);
$seconds -= $minutes * 60;
$time = sprintf("%02d:%02d:%02d", $hours, $minutes, $seconds);
$pay = $payPerHour * ($hours + $minutes/60 + $seconds/3600);
return [$time, $pay];
}
$times = ["01:00:00","00:15:00","00:00:30",]; // = 01:15:30 hours
$pay = 10;
[$totalTime, $totalPay] = sumTimesAndCalcPay($times, $pay);
print($totalTime);
print($totalPay);
