I am currently working on a PHP application that I plan to deploy on various cloud platforms, such as AWS, Azure, and Google Cloud. One question that has been bothering me is how to manage environment variables or secrets for these applications.
I understand the importance of securely storing sensitive information like database credentials, API keys, and other secret data. However, I am unsure about the best practices to follow in order to achieve this.
I would really appreciate it if anyone could share their knowledge and experiences regarding this matter. What methods or tools do you recommend for managing environment variables or secrets for PHP applications deployed on cloud platforms? Are there any particular techniques or services you have found to be reliable and secure?
Thank you in advance for your help!
