Run Correct Array function based on php session variable

As a very new php coder and newbie to web development, I need some advice and help, I have a .php script calculation that I include in the landing page. The script calculates the price based on user input during the form process. Without complicating things, and because I'm about to launch a dynamic landing page. The computed cost of script exits can be different due to the two different services we provide, so service 1 is cheaper than service 2.

How can I run an array function if the session variable is equal to a certain value, for example:

<?php
session_start();
if($_SESSION['service1'] == 'yes') {

Here is the Calculation.php script:

$data = array(
    array(
        'min' => "0",
        'max' => "100,000",
        'value' => 249
    ),
    array(
        'min' => "100,001",
        'max' => "200,000",
        'value' => 255
    )
);

function getAdjustedPrice($price, &$table) {
    $priceData = current(array_filter($table, function($value) use(&$price) {
        return $value['min'] <= $price && $value['max'] >= $price;
    }));
    return $priceData['value'];
}

$input = intval($_SESSION["servicecost"]);
printf("", 
       $input, 
       getAdjustedPrice($input, $data));

and if session variable 1 is not set to yes but is set to NO then run the second computation option and then I go out as option number 2 is basically service 2 and is a higher cost. ...

<?php
session_start();
if($_SESSION['service1'] == 'no') {

$data = array(
    array(
        'min' => "0",
        'max' => "100,000",
        'value' => 450
    ),
    array(
        'min' => "100,001",
        'max' => "200,000",
        'value' => 600
    )
);

function getAdjustedPrice($price, &$table) {
    $priceData = current(array_filter($table, function($value) use(&$price) {
        return $value['min'] <= $price && $value['max'] >= $price;
    }));
    return $priceData['value'];
}

$input = intval($_SESSION["servicecost"]);
printf("", 
       $input, 
       getAdjustedPrice($input, $data));

Hope this made sense, I tried to do it myself using the elseif state and do it like: if ($ _ SESSION ['service1'] == 'yes') {then run the code below it and then} else { if ($ _ SESSION ['service1'] == 'no') {but I haven't had any luck and constant stupid mistakes. Any advice or input is appreciated. Thank.

If I understood correctly, the following should do what you want:

<?php

session_start();

$service = $_SESSION['service1'] == 'yes'
           ? 'service1'
           : 'service2';


$data = array(

    'service1'=>array(
        array(
            'min' => "0",
            'max' => "100,000",
            'value' => 249
        ),
        array(
            'min' => "100,001",
            'max' => "200,000",
            'value' => 255
        )
    ),
    'service2'=>array(
        array(
            'min' => "0",
            'max' => "100,000",
            'value' => 450
        ),
        array(
            'min' => "100,001",
            'max' => "200,000",
            'value' => 600
        )
    )

);


function getAdjustedPrice($price, &$table)
{
    $priceData = current(array_filter($table, function($value) use(&$price) {
        return $value['min'] <= $price && $value['max'] >= $price;
    }));
    return $priceData['value'];
}

$input = intval($_SESSION["servicecost"]);

printf(
    "", 
    $input, 
    getAdjustedPrice($input, $data[ $service ])
);

Good luck!



The EDIT: . For the third service, you will need to add data to the array and check the correct value in the session, you can use a switch statement, the trick is assigning the correct service, I think you will need to store different values ​​in your session $ _SESSION ['service1'].

So your code will now look something like this:

<?php

session_start();

switch ($_SESSION['service1']) {
    case 'yes':
        $service = 'service1';
        break;
    case 'no':
        $service = 'service2';
        break;
    case '???????':
        $service = 'service3';
        break;
}


$data = array(

    'service1'=>array(
        array(
            'min' => "0",
            'max' => "100,000",
            'value' => 249
        ),
        array(
            'min' => "100,001",
            'max' => "200,000",
            'value' => 255
        )
    ),
    'service2'=>array(
        array(
            'min' => "0",
            'max' => "100,000",
            'value' => 450
        ),
        array(
            'min' => "100,001",
            'max' => "200,000",
            'value' => 600
        )
    ),
    'service3'=>array(
        array(
            'min' => "0",
            'max' => "100,000",
            'value' => 8888888888
        ),
        array(
            'min' => "100,001",
            'max' => "200,000",
            'value' => 9999999999
        )
    )

);


function getAdjustedPrice($price, &$table)
{
    $priceData = current(array_filter($table, function($value) use(&$price) {
        return $value['min'] <= $price && $value['max'] >= $price;
    }));
    return $priceData['value'];
}

$input = intval($_SESSION["servicecost"]);

printf(
    "", 
    $input, 
    getAdjustedPrice($input, $data[ $service ])
);
