Answer 1

1 - I don't see a constructor.

2 - Neither the class nor the connect() function has their closing brackets.

3 - Unless trigger_error() is defined elsewhere, it's an invalid function.

4 - You don't want to use global variables for database objects because other functions could overwrite them. You need to create a singleton to handle your database access for each database, otherwise you're risking major data integrity issues.

Answer 2

you could set up a database on your shopper computing device in case you desire. you may have hardship installation a Hypertext Preprocessor database. i think of you're pertaining to MySQL. you have a *lot* of interpreting to do in the previous you even evaluate doing what you have planned, in case you ask one in each of those question. Google "working a server from homestead" or some thing comparable.

Answer 3

well for one trigger_error is not a valid php function...
