Message:

I want to get the whole issuer name from cert.pem and I have this output:

Array, TSZEINVOICE-SubCA-1

the output should be like this:

CN=TSZEINVOICE-SubCA-1, DC=extgazt, DC=gov, DC=local

the code I am using :

$data = openssl_x509_parse(file_get_contents('cert.pem'));

$issuername = $data['issuer'];

echo implode(", ",$issuername);

but only I got the first is CN but cannot get DN values!

My Answer:
To get the complete issuer name from the cert.pem file in PHP, you can use the following code:

php
$data = openssl_x509_parse(file_get_contents('cert.pem'));
$issuername = $data['issuer'];
$issuerString = '';
foreach ($issuername as $key => $value) {
$issuerString .= $key . '=' . $value . ', ';
}
$issuerString = rtrim($issuerString, ', ');
echo $issuerString;


This code will iterate over the key-value pairs in the issuer array and concatenate them into a string in the format key=value, key=value, ... until all key-value pairs are processed. Finally, it will remove the trailing comma and space before echoing the complete issuer name.
