How can PHP developers efficiently store and retrieve multiple prices from a CSV file in a loop and pass them to another PHP script for calculation?

To efficiently store and retrieve multiple prices from a CSV file in a loop and pass them to another PHP script for calculation, you can use PHP's built-in functions like fgetcsv() to read the CSV file line by line, extract the prices, and then pass them to the calculation script. You can store the prices in an array and then iterate over the array to pass each price to the calculation script.

<?php

// Open the CSV file for reading
$csvFile = fopen('prices.csv', 'r');

// Initialize an empty array to store prices
$prices = [];

// Read the CSV file line by line
while (($data = fgetcsv($csvFile)) !== false) {
    // Assuming the price is in the first column
    $price = $data[0];
    
    // Store the price in the array
    $prices[] = $price;
}

// Close the CSV file
fclose($csvFile);

// Pass each price to the calculation script
foreach ($prices as $price) {
    // Call the calculation script with the price
    include 'calculation_script.php';
}

?>
