Print the next highest integer value by rounding up value with php

To make a round value from an decimal value like:

3.4 to 4
5.6 to 6

you can use the php ceil function, ceil - Round fractions down

its syntax is float ceil ( float $value )

example 

echo ceil(3.4);    // 4
echo ceil(9.999);  // 10


for a value Round fraction down you can use the floor()

example

echo floor(4.3);   // 4
echo floor(9.999); // 9
echo floor(-3.14); // -4


and one is the round() function which returns the nearest round value to the decimal

echo round(3.4);         // 3
echo round(3.5);         // 4
echo round(3.6);         // 4
echo round(3.6, 0);      // 4
echo round(1.95583, 2);  // 1.96
echo round(1241757, -3); // 1242000
echo round(5.045, 2);    // 5.05
echo round(5.055, 2);    // 5.06
