Hi

Is it alright to set a variable's value to nothing like this:

$variable == '';

Or is there some kind of place holder that needs to go there?

Many thanks

That's fine, although you did it wrong.

It should be $variable = '';

== means "is it equal to ...", = means "assigned to ...".

Also, you could use the unset function.

unset($variable).

The first way, assigning it to '', means it is set but has no value. using unset() means it is not set, and has no value, so it's like you never used it in the first place.

Or you can do
$variable = null;
Which by php.net standards is the correct way,

But it is EXACTLY what unset(); does, it's according on which you prefer to do, also a variable with no value is also considered null so $var = 0.0; would still be null... so yeah that's the other method other then what crazeD said.

No, $var would have a value of 0
