Larry,

 

What exactly does the colon do?

 

What does the array do?

 

I know they make the query safer, but how?

 

Thanks.

The colon creates a named placeholder. The array provides a value for the named placeholder(s). This approach makes queries safer as it results in a prepared statement, which prevents SQL injection attacks.
