openssl_x509_parse( OpenSSLCertificate|string$certificate, [bool$short_names = true] ): array|false

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.

Parameters

certificate

X509 certificate. See Key/Certificate parameters for a list of valid values.

short_names

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.
