Numbers

[sadair]

Anyone know how to verify if a variable is a whole positive number (no decimal points)?

You could use

if ($i%1) {
// if whole integer
}
else
{
//not whole integer
}

I think.....

I think you'd better use:

if(intval($i)== floatval($i))
{
     //If your value IS an int
}
else
{
     //NOT an int
}

Nota : intval($x) returns the integer part of $x

Well, you could try gettype()

though more reliable would be
is_int()
