How can PHP functions like floor, ceil, and round be used to manipulate numbers and eliminate decimal points?

PHP functions like floor, ceil, and round can be used to manipulate numbers and eliminate decimal points. Floor rounds a number down to the nearest integer, ceil rounds a number up to the nearest integer, and round rounds a number to the nearest integer. By using these functions, you can easily remove decimal points from numbers in PHP.

$number = 10.75;

$roundedDown = floor($number); // Result: 10
$roundedUp = ceil($number); // Result: 11
$rounded = round($number); // Result: 11
