Depends on paramaters like population of country HaircuttersCalculator will calculate approximate number of haircutters needed in this country.
Download the ZIP archive extract and include it in your program.
include 'path/to/class/Calculator.php';
Create an object and run calculate()
method:
$HC = new HaircuttersCalculator\Calculator();
echo $HC->calculate();
If everything went well you should see an approximate number of haircutters (176,201) needed with default parameters:
- Population: 50000000
- Mans rate: 54.0
- Time needed to shear man: 30
- Time needed to shear woman: 60
- How often the person shorn during the year: 12
- Haircutters working days (in the year): 345.25
- Haircutters working minutes per day: 432
You can set/change parameters in few ways:
// pass it on object creation
$HC = new HaircuttersCalculator\Calculator(50000,20);
// or even as array:
$HC = new HaircuttersCalculator\Calculator(array('population'=>20000));
// using setParameter() method:
$HC = new Calculator();
$HC->setParameter('population',50000001);
// using setParameter() method with array as argument:
$HC = new Calculator();
$HC->setParameter(array(
'man_rate'=>54,
'haircutters_working_days'=>10
));
You can check working copy visiting next URL:

Or you can host files provided in ZIP archive and access index.php
.
Also I provide an sample of CLI usage in file cli.php:
$: chmod +x cli.php
$: ./cli.php --population=20000
Input data:
Array
(
[population] => 20000
[man_rate] => 54
[shear_time_man] => 30
[shear_time_woman] => 60
[shears_per_year] => 12
[haircutters_working_days] => 345.25
[haircutters_working_minutes] => 432
)
Result: 71 haircutters needed.
You can pass --help
parameter to it to get some help:
$: ./cli.php --help
Usage:
./cli.php [--paramater1=value1 [--parameter2=value2 ... [--parameterN=valueN]]]
Allowed paramaters:
--population=integer Default 50000000
--man_rate=double Default 54
--shear_time_man=integer Default 30
--shear_time_woman=integer Default 60
--shears_per_year=integer Default 12
--haircutters_working_days=double Default 345.25
--haircutters_working_minutes=integer Default 432
To run tests you need to use next PHPUnit command:
phpunit --bootstrap tests/BootstrapLoader.php tests/HaircuttersCalculator/CalculatorTest.php
If everithing went well there must be output like:
OK (12 tests, 23 assertions)
