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

Si se tiene éxito, ésto contendrá el PKCS#12.
priv_key
El componente clave privada del archivo PKCS#12.

Contraseña de encriptación para desbloquear el archivo PKCS#12.
args
If your certificate is not password-protected, just use null or a blank string. Otherwise, this function won't work.
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);
?>
