Are there specific PHP libraries or functions recommended for generating CSV files that can help avoid formatting issues when opened in software like Excel?

When generating CSV files in PHP for use in software like Excel, it's important to handle special characters and formatting correctly to avoid issues when opening the file. To ensure compatibility, it's recommended to use PHP libraries like League\Csv or functions like fputcsv() that handle CSV formatting properly. 

```php
<?php

// Example using League\Csv library
require 'vendor/autoload.php';

use League\Csv\Writer;

$csv = Writer::createFromString('');
$csv->insertOne(['Column 1', 'Column 2', 'Column 3']);

// Add data rows
$data = [
    ['Row 1 Data 1', 'Row 1 Data 2', 'Row 1 Data 3'],
    ['Row 2 Data 1', 'Row 2 Data 2', 'Row 2 Data 3'],
];

$csv->insertAll($data);

// Output CSV to browser
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="example.csv"');
echo $csv->getContent();
```

In this example, we are using the League\Csv library to generate a CSV file with headers and data rows. The library takes care of handling special characters and formatting, ensuring compatibility with software like Excel. Finally, the generated CSV file is outputted to the browser for download.
