Our clients uses Azure AD for their operations and wanted to integrate the Azure AD MFA to our web app (PHP) for additional security. Is this possible without using the Microsoft Identity Platform (SSO)? I also cant seem to find a REST API for the Azure AD MFA. Any alternate options that I could use for implementing MFA? Some recommendations would be highly appreciated. Thank you.

If you have not already registered the php app in azure ad like below:
Quickstart: 
next
Or you can directly go for conditional access and select app required while creating access policy.
After all set up in conditional access, make sure to Enable policy and save ,to start authenticating with azure ad which requires MFA.
