What are the best practices for migrating from PHPExcel to PhpSpreadsheet or another alternative for reading Excel files in PHP?

Migrating from PHPExcel to PhpSpreadsheet or another alternative for reading Excel files in PHP is necessary due to PHPExcel being deprecated. To migrate, you can simply replace PHPExcel with PhpSpreadsheet in your codebase and update any deprecated functions or methods. Alternatively, you can explore other libraries like PHPSpreadsheet, which is actively maintained and offers more features. 

// Example code snippet for migrating from PHPExcel to PhpSpreadsheet
require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\IOFactory;

$inputFileName = 'example.xlsx';

$spreadsheet = IOFactory::load($inputFileName);
$worksheet = $spreadsheet->getActiveSheet();

$highestRow = $worksheet->getHighestDataRow();
$highestColumn = $worksheet->getHighestDataColumn();

for ($row = 1; $row <= $highestRow; $row++) {
    for ($col = 'A'; $col <= $highestColumn; $col++) {
        $cellValue = $worksheet->getCell($col . $row)->getValue();
        echo $cellValue . ' ';
    }
    echo "\n";
}
