See openssl-verification-options (1) for more information on trust settings. This option can be specified more than once to load certificates from multiple sources.
openssl_verify () verifies that the signature is correct for the specified data using the public key associated with public_key. This must be the public key corresponding to the private key used for signing.
20 The problem is, that openssl -verify does not do the job. As Priyadi mentioned, openssl -verify stops at the first self signed certificate, hence you do not really verify the chain, as often the intermediate cert is self-signed.

openssl_verify () vérifie que la signature signature est correcte pour les données data, et avec la clé publique public_key. Cette clé doit être la clé publique correspondant à la clé privée utilisée lors de la signature.
One or more target certificates to verify, one per file. If no certificates are given, this command will attempt to read a single certificate from standard input.
