If you need to provide multiple additional certificates, the 'extracerts' argument needs to be an array with one certificate per element:

<?php

$args = array(

    'extracerts' => array(

        0 => '-----BEGIN CERTIFICATE----- cert1 ...',

        1 => '-----BEGIN CERTIFICATE----- cert2 ...',

        // ...

        )

    );

?>



You can use this to prepare a PEM.



<?php

$pemChain = '...';

preg_match_all('/(-----BEGIN CERTIFICATE-----.*?-----END CERTIFICATE-----)/si', $pemChain, $matches);

$args = array('extracerts' => $matches[0]);

openssl_pkcs12_export($signed_csr, $cerificate_out, $private_key_resource, $passphrase, $args);

?>

in order to export a private key to pkcs12 format, the input certificate must contain both private and associated public key in PEM format ,  



-----BEGIN RSA PRIVATE KEY-----

-----END RSA PRIVATE KEY-----



-----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----



else this function might return the following error "openssl_pkcs12_export(): cannot get cert from parameter 1"

If you want to include CA-Certificates in the PKCS12 it can be accomplished by using the $args parameter.

<?php

$args = array(

               'extracerts' => $CAcert,

               'friendly_name' => 'My signed cert by CA certificate'

              );

openssl_pkcs12_export($signed_csr, $cerificate_out, $private_key_resource, $passphrase, $args);

?>

Example:





<?php


$key = openssl_pkey_get_private(Private_Key, Password);





openssl_pkcs12_export(Certificate, $iis, $key, Password);


?>

If your certificate is not password-protected, just use null or a blank string.  Otherwise, this function won't work.
