(PHP ActiveX) Transition from Crypt2.GetSignerCertChain to Crypt2.LastSignerCert

Provides instructions for replacing deprecated GetSignerCertChain method calls with LastSignerCert.

Note: This example requires Chilkat v11.0.0 or greater.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// Do the equivalent using LastSignerCert, and then get the certificate chain from the cert.
// Your application creates a new, empty Cert object which is passed 
// in the last argument and filled upon success.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Cert')
