遇到openssl_x509_parse（）函数问题

Question

I'm having trouble with the openssl_x509_parse() function

$parsed_cert = openssl_x509_parse(file_get_contents('/home/my_location/aaa010101aaa__csd_01.cer'));

the function is returning a false and I'm unsure about the reasons. Maybe the certificate file must be in .pem or .crt?

EDIT: the code was ok, but the format of the file was the issue, so i had to transform it into a .crt from the .cer original.

Answer 1

After seeing the example from manual page, your code seems fine. Problem may be in file_get_contents.

Please try the following and check the if file is valid.

$file = file_get_contents('/home/my_location/aaa010101aaa__csd_01.cer');
$parsed_cert = openssl_x509_parse($file);

Now check what is file. Is it exists or a valid certificate file?
