Question

This bit of code:

$hour = 2.2;
    if (floor($hour) > 1) {
        $str = $str . floor($hour) . " hours";
    }
    else if (floor($hour) === 1) {
        $str = $str . floor($hour) . " hour";
    }
echo $str;

Will output: 2 hours

However, this bit:

$hour = 1.2;
    if (floor($hour) > 1) {
        $str = $str . floor($hour) . " hours, ";
    }
    else if (floor($hour) === 1) {
        $str = $str . floor($hour) . " hour ";
}
echo $str;

Will not output 1 hour, because the condition for the else if does not match for some reason. Why is that?

Answer 1

Floor returns a float, you’re testing for an integer.

Edit for clarity:

<?php
$str = "";
$hour = 1.2;
    if (floor($hour) > 1) {
        $str = $str . floor($hour) . " hours, ";
    }
    else if ((int) floor($hour) === 1) {
        $str = $str . floor($hour) . " hour ";
}
echo $str;
