Fixing the PHP empty function

Question

PHP has the habit of evaluating (int)0 and (string)"0" as empty when using the

empty()

function. This can have unintended results if you expect numerical or string values of 0. How can I "fix" it to only return true to empty objects, arrays, strings, etc?

Answer 1

This didn't work for me.

if (empty($variable) && '0' != $variable) {
  // Do something
}

I used instead:

if (empty($variable) && strlen($variable) == 0) {
  // Do something
}
