[RESOLVED] Evaluate if NUMBER

[zzz]

I have a form field that must only contain a numeric value

Is this the best way to evaluate:

if (is_int($myvar) && $myvar > 0)

Or shall I use is_numeric

My number has to do with number of people and can not have decimails or negative numbers.

Then I think that is_int is the best since numbers with decimals is numbers with is_numeric. To make it into a number you can typecase:

$test1 = "8"; // Is a string with the text "8"
$test2 = (int)$test1; // test2 becomes an integer

I don't know if you have to transform it to a number, but at least now you know how to do.

Probably the most efficient method would be to use ctype_digit():

if(ctype_digit($value) && $value > 0)
{
  // it's a positive integer
}
else
{
  // it's something else
}
