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);
?>

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

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);
?>

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"

Example:

<?php
$key
= openssl_pkey_get_private(Private_Key, Password);

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