[fw-general] Question

[Daniel Latter]

Hi All,

forgive me for the simplistic question but looking through ZF source I
see if statements structured like so:

if ('' === $value) {
..
}

is this just to protect against $value being empty?

Consequently, would I be better doing this:

while(false != ($attribute = $result->fetch_assoc())) {
...
}

instead of:

while($attribute = $result->fetch_assoc()) {
..
}

TIA

Dan
