Why does this code output this ?

Question

why does the function:

function longtime ($timestamp)
{
return longdate ("l F jS Y", $timestamp);
}
echo date(time());
//output: 1528819983

instead of the this "correct" one which is :

function longdate ($timestamp)
{
return date ("l F jS Y", $timestamp);
}
echo longdate(time());
//output: Tuesday June 12th, 2018

Answer 1

i believe date returns a certain amount of time units passed since some year. a quick google search should help you with the details
