Getting Fatal error: Class 'ProtobufMessage' not found in /home/ashwinn/public_html/php-protobuf/example/pb_proto_foo.php on line 10 when trying to execute from browser about php-protobuf

[enumag]

... Ok I found the problem. My protobuf.ini contained extensions=protobuf.so instead of extension=protobuf.so.

Module is not loaded automatically by your php installation.

Thanks for your response. I have already included Protobuf.so in php.ini. So it should be executable from browser also ,right??

[hjagodzinski]

Make sure you edited the right php.ini file (not just one for CLI interface).

[ashwinnasare]

I have edited /etc/php.ini from server.
How can I verify whether I have edited the correct php.ini?using phpinfo?

[hjagodzinski]

Yeap, phpinfo() function should provide you with this information.

I'm getting the same problem. phpinfo reports that file /etc/php/7.2/cli/conf.d/20-protobuf.ini was loaded and the file contains extensions=protobuf.so. But still I'm getting Fatal error: Class 'ProtobufMessage' not found. php -m does not contain protobuf either. Why?

[hjagodzinski]

@enumag make sure you placed protobuf.so in a directory where PHP looks up for extensions. You can find this directory by running command:

$ php-config --extension-dir

[enumag]

@hjagodzinski Yes, protobuf.so is indeed in php-config --extension-dir. But it still isn't in php -m. I have no idea what I might have missed.
