php problem in isset and empry

Question

array(4) { ["id"]=>  int(0) ["pass"]=>  string(0) "" ["log_in"]=>  string(3) "no"  } 

now the problem in id when using isset it return true because its 0 when using empty i think its doing the same please help me is determine the best function to know its set or not

Answer 1

empty return false for these:

"" (an empty string)
0 (0 as an integer)
"0" (0 as a string)
NULL
FALSE
array() (an empty array)
var $var; (a variable declared, but without a value in a class)

You need to use isset instead to check if it is there.

See:

empty vs isset

Answer 3

a simple if condition will do for you

if(id)
{
}

try it if it works.

Answer 4

if($array['id'] === 0) {
  true
} ?

Answer 5

if id is a database id is positive integer

so if($id>0) is one simple solution

OR

preg_match('#^[0-9]*$#', $id)
