Hi,

I would like to say this:-

if variable 1 is either 2 less, 1 less, the same, 1 more or 2 more than variable 2 do an action.

can anybody help me on how i would code that!

im not shore if i understand you but is this what you are looking for?

 

if ($veriable < $veriable + 2 && $veriable > $veriable - 2){
// do somthing funky
}

 

if not can you clean up what you said so it makes a little more sence

Do you mean to say if (var1 >= (var2 -2) && var1 <= (var2 + 2)) ?

sound tough to me.

<?php
if(abs($var1-$var2) <= 2){
//Do stuff
}

sorry. its so hard to explain. if variable 1 is i inbetween the range or two more or two less do an action. i have done it the long way round. here is what i ment...

if ($a == $a1) {
//the same action
} elseif ($a == $a1 + 1) {
//the same action
} elseif ($a == $a1 + 2) {
//the same action
} elseif ($a == $a1 - 1) {
//the same action
} elseif ($a == $a1 - 2) {
//the same action
}
