What are the potential pitfalls of using fgetcsv to read Excel files in PHP?

One potential pitfall of using fgetcsv to read Excel files in PHP is that it may not handle Excel-specific formatting or features correctly, leading to data loss or corruption. To solve this issue, it is recommended to use a library like PHPExcel or PhpSpreadsheet, which are specifically designed for working with Excel files in PHP. 

// Example using PhpSpreadsheet to read an Excel file
require 'vendor/autoload.php'; // Include PhpSpreadsheet library

use PhpOffice\PhpSpreadsheet\IOFactory;

$spreadsheet = IOFactory::load('example.xlsx'); // Load Excel file
$worksheet = $spreadsheet->getActiveSheet();

foreach ($worksheet->getRowIterator() as $row) {
    $cellIterator = $row->getCellIterator();
    $cellIterator->setIterateOnlyExistingCells(FALSE); // Loop through all cells, even empty ones
    
    foreach ($cellIterator as $cell) {
        echo $cell->getValue() . "\t"; // Output cell value
    }
    echo "\n";
}
