Variables and switch() function

[Schlo_50]

Hi there, Couple of questions.

 

Is is possible to define my variable $low_boundary to be any number from 0 - 20000?

 

Or is there a better way to do this?

 

Im testing out the switch() function for fun and am setting my search variable to be 13999 for example. I want to have three cases in total acting as boundaries. ($low_boundary = 0 - 20000, $med_boundary = 21000 - 40000 and $high_boundary = 41000 - 100000)

 

I have this so far, but don't know how to make my cases become parameters as it were.

 

<?php
$wage = "13999";

$low_boundary = "";
$med_boundary = "";
$high_boundary = "";

print "Desired Wage: £$wage<br />";
switch ($wage){
case "$low_boundary":
	print "Low Band: £0 - £20000";
	break;
case "$med_boundary":
	print "Medium Band: £21000 - £40000";
	break;
case "$high_boundary":
	print "High Band: £41000 - £100000";
	break;	
default:
	print "Your desired wage is too high.";
	break;
}
?>

 

Can somebody help me out? Thanks, I'd really like to learn the boundaries thing and get the switch funtion working nicely. I think switch could be very useful in the future!

 

Thanks

i think if else is more applicable in this situation....

You could use a switch on true:

 

<?php
//define boundaries
$low_boundary = '0-19999';
$med_boundary = '20000-39999';
$high_boundary = '40000-100000';

//explode at dashes to get an array with lowest and highest values for each level
$low = explode('-', $low_boundary);
$med = explode('-', $med_boundary);
$high = explode('-', $high_boundary);

//set sample wage
$wage = '13999';

//do the switch!
switch(true) {
case $wage >= $low[0] && $wage <= $low[1]:
	echo 'Low Band: £0 - £19999.';
	break;
case $wage >= $med[0] && $wage <= $med[1]:
	echo 'Medium Band: £20000 - £39999.';
	break;
case $wage >= $high[0] && $wage <= $high[1]:
	echo 'High Band: £40000 - £100000.';
	break;
default:
	echo 'Out of bounds.';
}
?>
