-----END CERTIFICATE-----

and i want to get the signature value that is in this certificate.

i tried many solutions and this the closest one to the needed result.

$cert = openssl_x509_read($certificate);

openssl_x509_export($cert, $out, FALSE);

echo $out;

this solution gives me the whole information about the certificate , also the signature with them , but as string :

this is the signature value :

the problem now , that this is a string, is there a way easier than this , that gives me object or something like that ?

i have tried openssl_x509_parse also , but it does not give me the signature
