But here’s the thing: that’s not a very efficient way of working.
On top of that, you’re usually focused on the last step
(like printing out the tables), and so you may not spend much
time figuring out the best way to handle the in-between
steps. You might not use { } to simplify the statement that
prints $row[0], or you may skip a die because you’re thinking
about HTML output, not handling the case where the database
password isn’t right.
