I am really stuck on the code, and I dont know how to solve it. I am trying to calculate how much I earn a day. The problem is that I earn different amount depending on which hour on a day it is. Fx:

08.00 - 06.00  (Morning) -> 150
06.00 - 10.00 (Evening) -> 200
10.00 - 11.00 (Night) -> 250

So I have calculated how much hours I work a day with this code:

<p>Choose Your Work TIme</p>
    <form method='post'>
        <select name="s1" required>
        <option>Choose Start Time</option>

Lets say I work from 10.00 in the morning to 11.00 in the night. That would mean I work 13 hours. But how can i calculate how much money I earn in the above time period? I have tried the following but nothing is working:

<?php


// create timeblocks:
// 8  = from 0.00 untill 8.00 
// 18 = from 8.00 untill 18.00
// 24 = from 18.00 untill 0.00
$timeblocks=array(
    8*60,
    18*60,
    24*60
    );
//earnings PER 15 MINUTES in the above timeblocks
$money=array(
    146/4,
    204/4,
    244/4
    );
$earned=0;

//create a start and end time object
$start=date_create_from_format('Y-m-d H:i:s', $_POST['s1']);
$end=date_create_from_format('Y-m-d H:i:s', $_POST['s2']);

//calculate how many blocks of 15 minutes
$diff=$start->diff($end);
$steps=(($diff->d)*3600+($diff->h)*60+($diff->i))/15;

//loop every 15 minutes
for($i=0;$i<=$steps;$i++){
    //start with the start date, and add 15 minutes every time
    if($i!==0)$start->add(new DateInterval('PT15M'));

    //calculate the time 
    $time=((int)($start->format('H')*60)+(int)($start->format('i')));

    //look in timeblocks what block we are in and get the earnings from that block
    for($block=0;$block<3;$block++){
        if($time<=$timeblocks[$block]){
            $earned+=$money[$block];
            echo '$'.$money[$block].' earned at '.$start->format('d-m-Y H:i:s').'<br>';
            break;
            }
        }
    }

echo 'TOTAL earned: $'.$earned; 


?>

I hope somebody can help me.

Best Regards Mads

    I'm sure there are better solutions, but this works :-)

    [edit] to meet OP's new requirements

    //If you haven't done allready SET your timezone!!
date_default_timezone_set('Europe/Amsterdam');

// create timeblocks:
// 8  = from 0.00 untill 8.00 
// 18 = from 8.00 untill 18.00
// 24 = from 18.00 untill 0.00
$timeblocks=array(
    8*60,
    18*60,
    24*60
    );
//earnings PER 15 MINUTES in the above timeblocks
$money=array(
    100/4,
    10/4,
    50/4
    );
$earned=0;

$_POST['s1']='18.30';
$_POST['s2']='8.30';

//sanitize your post: only numbers and a dot allowed
$s1=preg_replace("/[^0-9|.]/","",$_POST['s1']);
$s2=preg_replace("/[^0-9|.]/","",$_POST['s2']);

if($s1==$s2){
    //no working time: do something
    //NOTE: this assumes nobody working for 24 hours, because if you start at 
    //6pm day 1 and end 6pm on the next day (==24 hours) the times are the same 
    //as well.
    }

//if second time smaller then first time, we are in the next day and add 24 hours
$add=0;
if($s1>$s2)$add=24;

//make hours and minutes
$s1=explode('.',substr('0'.$s1,-5));
$s2=explode('.',substr('0'.$s2,-5));

//create a start and end time object
$start=new Datetime('now');
$start->setTime($s1[0],$s1[1]);

$end=new Datetime('now');
$end->setTime($s2[0]+$add,$s2[1]);


//calculate how many blocks of 15 minutes
$diff=$start->diff($end);
$steps=(($diff->d)*3600+($diff->h)*60+($diff->i))/15;

//loop every 15 minutes
for($i=1;$i<=$steps;$i++){
    //start with the start date, and add 15 minutes every time
    $start->add(new DateInterval('PT15M'));

    //calculate the time 
    $time=((int)($start->format('H')*60)+(int)($start->format('i')));

    //look in timeblocks what block we are in and get the earnings from that block
    for($block=0;$block<3;$block++){
        if($time<=$timeblocks[$block]){
            $earned+=$money[$block];
            echo '$'.$money[$block].' earned at '.$start->format('d-m-Y H:i:s').'<br>';
            break;
            }
        }
    }

echo 'TOTAL earned: $'.$earned;
