OpenSSL PHP Function doesn't work

Question

Hi, I'm looking for days how to translate this command to OpenSLL php function:

$ openssl pkcs8 -inform DER -in aaa010101aaa_CSD_01.key -out AAA010101AAA.key.pem
Enter Password: a0123456789

This work perfect, but I can't (I don't know) use the correct function of PHP OpenSSL http://www.php.net/manual/es/ref.openssl.php

I have made this for .cer working perfect:

command : openssl x509 -inform DER -outform PEM -in aaa010101aaa_CSD_01.cer -out AAA010101AAA.cer.pem

PHP equivalent:

function der2pem($der_data) {
    $pem = chunk_split(base64_encode($der_data), 64, "\n");
    $pem = "-----BEGIN CERTIFICATE-----\n".$pem."-----END CERTIFICATE-----\n";
    return $pem;
}

$fp = fopen("llaves/aaa010101aaa_CSD_01.cer", "r");
$priv_key = fread($fp, 8192);
fclose($fp);

echo der2pem($priv_key);

It's perfect, giving it to me the PEM. But doesn't work for the .key, just for the .cer, I obtain on OpenSSL this for .key using the funcion on PHP:

The same function on php give me:

lol i guess your try to made a system for SAT Mexico i try to find the same solution over PHP but is not posible using just PHP

ever whit your function der2pem(this function had like 4 years, write by "dan-AT-NOSPAM danschaferDOTnetTT" at php.net) because this file had password protection you need use exec command
