That doesn't actually answer the question, it just changes the key/value
pairs around. There is a built-in function for this in PHP, but it's not
what the OP asked for.

I misread the question as flipping array keys, my mistake.

I'd use a loop for something like that:

$new_array = array('0-300'=>0, '301-400'=>0, '401-500'=>0, '501+'=>0);
foreach($old_array as $a)
{
switch(true)
{
case $a <= 300:
{
$new_array['0-300']++;
break;
}
case $a <= 400:
{
$new_array['301-400']++;
break;
}
case $a <= 500:
{
$new_array['401-500']++;
break;
}
default:
{
$new_array['501+']++;
break;
}
}
}

sort() operates in the array. It does not return a new array, just a
bool to indicate success or not.
