A PHP library that adds SAML 2.0 support to PHP applications, enabling them to act as a Service Provider for single sign-on with identity providers. It handles SAML request/response generation, validation, metadata, and XML signature verification.

Use cases

• add SAML single sign-on to a PHP app
• integrate with Okta or Azure AD via SAML
• implement a SAML service provider in PHP
• validate SAML responses and signatures
• generate SAML metadata XML
• support enterprise SSO login in a PHP application

When to choose

• you need SAML 2.0 SP functionality in a PHP application
• you must integrate with enterprise identity providers that only support SAML
• you want a well-tested library with security hardening against signature wrapping and XEE attacks

When to avoid

• your application only needs OAuth2 or OpenID Connect rather than SAML
• you are not using PHP
• you need an identity provider implementation rather than a service provider
