Checking if a number is within a certain range of other another.

[Michdd]

I need help making something that will check if a number (Set in a variable) is within 5 numbers + or - of another number. What would the if statement for this look like?

try

 

<?php
$number = 5

$check_against = 15;
$range = 5;
$low_range = $range*-1;
$v = $number-$check_against;

if($v <=$range  && $v >=$low_range){
#its good
}
else{
#outta range
}
?>
