(PHP 5 >= 5.2.2, PHP 7)
RSA example with random key generation. RSA example with PKCS #1 Padding. RSA example with OAEP Padding and random key generation. An example of using RSA to encrypt a single asymmetric key. Simple Digital Signature Example: 36.38.7. Creates a 1024 bit RSA key pair and stores it to the filesystem as two files. Generally the approach is to encrypt the private key with a symmetric algorithm using a key derived from the passphrase via a key derivation function. A classic example of a suitable key derivation function is PBKDF2 from RFC 2898 - PKCS #5: Password-Based Cryptography Specification Version 2.0.
Generating public private key pairs for use in an application free. Enter passphrase (empty for no passphrase):It’s up to you whether you want to use a passphrase.

On success, this will hold the PKCS#12.
priv_key
Private key component of PKCS#12 file. See Public/Private Key parameters for a list of valid values.
pass
Encryption password for unlocking the PKCS#12 file.
args
Key | Description |

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);
?>

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);
?>
