Utility to emulate goalseek function in PHP. This fork was made for very specific project, and there is no promise to keep any BC.

This library is a fork of [PHP-Excel-GoalSeek](https://github.com/juanjomip/PHP-Excel-GoalSeek)

Install
-------

[](#install)

Use package from packagist.

```
composer require p4/excel-goalseek
```

Usage
-----

[](#usage)

```
//Define function which for which the value should be found
$callbackTest = function callbackTest($input) {
    $inputForCallbackTest2 = $input * 8;
    return $inputForCallbackTest2 - 12;
};

//Instantiate goal seek class
$goalseek = new ExcelGoalSeek();
//$goalseek->debug = true;

//I want to know which input needs callbackTest to give me 301
$expected_result = 300;

//Calculate the input to get you goal, with accuracy
$input = $goalseek->calculate($callbackTest, $expected_result, 5);

//Voilá!
echo "\$input: " . $input . "";

//Let's test our input it is close
$actual_result = $callbackTest($input);
//Searched result of function
echo "Searched result of $callbackTest(\$input) = " . $expected_result . "";
//Actual result of function with calculated goalseek
echo "Actual result of $callbackTest(" . $input . ") = " . $actual_result . "";
//If difference is too high, you can improve the class and send me it your modifications ;)
echo "Difference = " . ($actual_result - $expected_result);
```
