floor() does ceil()'s opposite it returns the lower number
of the fraction
floor(3.0)=3
floor(3.1)=3
floor(3.3)=3
floor(3.5)=3
floor(3.7)=3

Answer / nilsoft
ceil()
Returns the next highest integer value by rounding up value
if necessary.
<?php
echo ceil(4.3); // 5
echo ceil(9.999); // 10
echo ceil(-3.14); // -3
?>
floor()
Returns the next lowest integer value by rounding down value
if necessary.
<?php
echo floor(4.3); // 4
echo floor(9.999); // 9
echo floor(-3.14); // -4
?>
