Codeigniter迁移mysql到mysqli连接错误

Long time reader, first time poster,

I found this error pinging a webservice from my app after doing a migration to php 7.2 hosting environment from 5.6:

PHP Fatal error:  Uncaught Error: Call to undefined function mysql_connect() in …system/database/drivers/mysql/mysql_driver.php

After some research, this looked like a simple one line fix in codeigniter framework from: $db['default']['dbdriver'] = 'mysql'; to:

$db['default']['dbdriver'] = 'mysqli';

When I make a server request from the app after this change, my error log returns nothing but is still not loading in the app as before. I have read other posts on the topic suggesting I would need to make other mysql->mysqli changes, tried doing this in driver files also with no luck.
