If you encounter the following error:
"PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mongodb.so'
- /usr/lib64/php/modules/mongodb.so: undefined symbol: php_json_serializable_ce in Unknown on line 0"
For a detailed explanation, please visit:

TLDR: You need to load the mongodb.so extension after the json.so
extension
Special thanks to Derick Rethans for pointing this out!
