I need to do a search on the database and according to the value found within a range of values should return a specific value.
For example, if you find values from 1 to 4, you should return 1, finding from 5 to 8, you should return 2.
The multiple of a given value is required.
What you need is the ceil () function, which rounds values up.
So you can use:
$valorRetornado = ceil($seuValor / 4);
For example:
echo ceil(1 / 4); // dá 1
echo ceil(4 / 4); // dá 1
echo ceil(5 / 4); // dá 2
echo ceil(8 / 4); // dá 2
echo ceil(54654 / 4); // dá 13664
