Are there any best practices to follow when trying to access and manipulate vCard files using PHP?

When trying to access and manipulate vCard files using PHP, it is recommended to use a library that supports vCard parsing and manipulation. One popular library for handling vCard files in PHP is Sabre\VObject. This library provides a simple and efficient way to read, write, and manipulate vCard files.

// Include the Sabre\VObject library
require 'vendor/autoload.php';

// Load the vCard file
$vcard = Sabre\VObject\Reader::read(file_get_contents('example.vcf'));

// Access and manipulate vCard properties
echo $vcard->VERSION;
$vcard->FN = 'John Doe';

// Save the modified vCard file
file_put_contents('modified.vcf', $vcard->serialize());
