I've created a tool called Rector, that handles instant upgrades. There is also mysql → mysqli set.

It handles:

• function renaming
• constant renaming
• switched arguments

• non-1:1 function calls changes, e.g.

  $data = mysql_db_name($result, $row);
  

  ↓

  mysqli_data_seek($result, $row);
  $fetch = mysql_fetch_row($result);
  $data = $fetch[0];
  

Just use it on your code:

composer require rector/rector --dev
vendor/bin/rector process src --set mysql-to-mysqli

I've already run it on 2 big PHP projects and it works perfectly.
