variable conparison tests

[truegilly]

Hi

was wondering is anyone could shed any light on this no doute simple problem.

lets say i have some variables, [color=red]$Actual [/color]and [color=red]$Target[/color].

[code]$Target = 5;
$Actual = 3;[/code]

Both are integers and get their values from a database.

see the example below its all very simple

[code]if ($Target == $Actual)
{
$colour = "green";
return $colour;
}
else if ($Actual < $Target)
{
$colour = "red";
return $colour;
}
else
{
$Actual > $Target;
$colour = "blue";
return $colour;
}[/code]

what i would like to add to this statement is if $actual is less than the $Target by 2, it will return "Amber".

so the expression will be something like this...

[code]
if ($Actual < $Target by 2) {
return "amber"
}
[/code]

can anyone explain how this is done ?

thanks in advance  :P

if(($Actual-$Target)==2)
{
  $color="Amber";

Suzzane2020 has given you the only way you can achieve this...

You may also use

if($Target==$Actual-2) or if($Target+2==$Actual)... hehehehehehe :p... but the point is that I don't think there's any other real solution.

thanks for your help,

heres my code. the problem is is the red section seem to take over and doesn't allow the amber to show, could you adjust my code so it will work ?

[code] if ($Target == $Actual)
{
$colour = "green";
return $colour;
}
if(($Actual-$Target)==2)
{
  $color="Amber";
  return $color;
}
else if ($Actual < $Target)
{
$colour = "red";
return $colour;
}
else
{
$Actual > $Target;
$colour = "blue";
return $colour;
}[/code]

thanks

add a part over here

else if (($Actual < $Target) &&( ($Actual-$Target)!=2))

{
$colour = "red";
return $colour;
}

Hi guys,

thanks for all your help. Its now working and the code is below for anyone who has a similar problem

[code] if ($Target == $Actual)
{
$colour = "green";
return $colour;
}
else if(($Target-$Actual)==2 || ($Target-$Actual)==1)
{
  $color="Amber";
  return $color;
}
else if ($Actual < $Target)
{
$colour = "red";
        return $colour;
}
else
{
$Actual > $Target;
$colour = "blue";
return $colour;
}[/code]

Truegilly  :P

You'll need to tweak that.

If your actual is less than your target by 1, it will be red, but if it's 2, it will be amber, and greater than two are back to red.
