Creating function to display shipping rate based on weight

[voight-kampff]

I've just started to create a function that will use two variables on a website. The first variable is the combined weight of an order and the second is three ship rates. I am using a plugin that gives me these rates but doesn't allow me the option to only show the appropriate rate during checkout. This function would hopefully only display the correct option based on the weight variable.

In the code below I'm trying to say if weight <= 2 then show A, if weight => 3 but < 5 show B, else show C

<?php
function calculateWeightFlag($weight)
{
if($weight <=2)
{
setWeightFlagA();
}
elseif($weight =>3 || $weight <5)

{
setWeightFlagB();
}
else
{
setWeightFlagC();
}
}
?>

The syntax error starts on "elseif" line.

When posting code, please use the formatting tags described in the FAQs to format your code. Also, when you get an error message, it's helpful to others to tell them what it says.

You mean [font=monospace]>=[/font], not [font=monospace]=>[/font].

also this line:

elseif($weight >=3 || $weight <5) 

will always evaluate to true for all numbers

it should be

elseif($weight >=3 && $weight <5) 

are you aware values between 2.1 to 2.9 will trigger condition c?
