How can PHP developers efficiently map column names from a CSV file to variables in their code?

When working with CSV files in PHP, developers often need to map column names from the file to variables in their code. One efficient way to do this is by using the fgetcsv() function to read the first row of the CSV file, which typically contains the column names. Then, developers can create an associative array mapping the column names to variable names for easy access in the rest of the code. 

<?php

$csvFile = 'data.csv';
$handle = fopen($csvFile, 'r');

if ($handle !== false) {
    $headers = fgetcsv($handle);

    while (($data = fgetcsv($handle)) !== false) {
        $row = array_combine($headers, $data);

        // Access variables using column names
        $column1 = $row['Column1'];
        $column2 = $row['Column2'];
        $column3 = $row['Column3'];

        // Use the variables as needed in the code
        echo $column1 . ' - ' . $column2 . ' - ' . $column3 . PHP_EOL;
    }

    fclose($handle);
} else {
    echo 'Error opening the CSV file.';
}
?>
