Thanks, now you cleared thinks to me, it appears parseCertificate is for parsing let's encrypt full chain certificate.

from acmecert.

The parseCertificate function can only parse x509 certificates, it can not parse certificate requests (CSR).

Unfortunately there is no function in the PHP OpenSSL-Extension which allows full parsing of CSRs like there is for x509 certificates.

As a workaround you could use the openssl command to parse the CSR:

# openssl req -noout -text -in file_containing_your.csr
Certificate Request:
