问题
Suggested that we have this SQL text with 3 MySQL commands:
show tables;
some nonesense command which makes error;
show tables;
The first and third SQL are valid, the second isn't. So, when passing this SQL text to mysqli_multi_query, does MySQL stop execution at the second command (error one) or it tries to go on until the last command? Coz it is dangerous if those commands after the error one relies on the error one.

No, if one query fails the rest will not be executed. See this comment over at the documentation for mysqli_multi_query, which makes this clear and also showcases one way to check for errors.
