# openssl_x509_parse

(PHP 4 >= 4.0.6)

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

## Description

``array openssl_x509_parse` (mixed x509cert [, bool shortnames])`

Warning
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change in a future release of PHP without notice. Be warned and use this function at your own risk.

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. `shortnames` controls how the data is indexed in the array - if `shortnames` 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.

> Note: This function was added in 4.0.6.
