openssl_x509_parse — Parse an X509 certificate and return the information as an array

Description

function 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.

Return Values

The structure of the returned data is (deliberately) not yet documented, as it is still subject to change.
