openssl_x509_parse returns information about the supplied certificate, including fields such as subject name, issuer name, purposes, valid from and valid to dates etc.
X509 certificate. See Key/Certificate parameters for a list of valid values.
short_names controls how the data is indexed in the array - if short_names is true (the default) then fields will be indexed with the short name form, otherwise, the long name form will be used - e.g.: CN is the shortname form of commonName.
The structure of the returned data is (deliberately) not yet documented, as it is still subject to change.
|certificate accepts an OpenSSLCertificate instance now; previously, a resource of type OpenSSL X.509 was accepted.
