array openssl_x509_parse(mixed $x509cert[, bool $shortnames = true])
openssl_x509_parse() returns information about the supplied
x509cert, including fields such as subject name, issuer name, purposes, valid from and valid to dates etc.
The structure of the returned data is (deliberately) not yet documented, as it is still subject to change.
- mixed $x509cert:
- bool $shortnames [ = true]:
shortnamescontrols how the data is indexed in the array - if
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.
