I think I finally understand what you are trying to do. I don't see
any reason why you need to use the token functions, and I would
recommend using array functions instead (also, it is exceedingly easy
to sort the elements of an array... see the end).
I believe this will do what you are trying to do:
//Tokenizer for Babu
$str = '10,12,14-18';
$commas = explode(',', $str); // $commas will be an array of three
items in this case
// Final Values will go into the $final array
$final = array();
foreach ($commas as $value) {
// If one of the $commas elements contains a dash, we need to
get the range between them!
if (strstr($value, '-')) {
// Explode based on the dash. This code assumes there will
only be a single dash
$rangeValues = explode('-', $value);
foreach (range($rangeValues[0], $rangeValues[1]) as $number) {
$final[] = $number;
}
} else {
// If $value does not contain a dash, add it directly to the
$final array
$final[] = $value;
}
}
echo "All your values in the range $str are ".implode(' ', $final);
// Prints "All your values in the range 10,12,14-18 are 10 12 14 15
16 17 18"
In your last email, you had some of the values given out of order:
1. 20,21-24
2. 21-24,20
3. 10,20,21-24,25,26,30
To make sure the $final values are always ascending, just do this at
the end:
sort($final);
Done!!

foreach ($finaltokens as $ftoken){

echo "<br />";
}
the ouput prints only 10,12 but not 14,15,16,17,18. where is the
problem.
