How can the compatibility between PHP and Apache be ensured when upgrading to a 64-bit version of PHP?

To ensure compatibility between PHP and Apache when upgrading to a 64-bit version of PHP, it is important to make sure that the PHP module is compiled with the same architecture (64-bit) as the Apache server. This can be done by downloading the appropriate 64-bit version of PHP and configuring it to work with the 64-bit Apache server.
