empty() OR isset()

Sharif

What do you guys prefer to use? What is better to use? isset() or empty()?

ir4z0r

well, none of them 😃

if ($var) {}
or
if (!$var) {}

generally, the functions are different and have their own special cases,
but mostly empty() will be more useful, cause empty values aren't
useful (in most cases)

Sharif

Would you recommend using this?:

if (empty($variable))

if ($var == '')

hmm, there may be a reason, why empty() exists, but I think
the second one is easier to read.
Some time ago I used to use the 2nd, now I prefer just if($var) {}

why do you care anyway? You seem to be quite happy, not having
bigger problems 😉
