Answer 1

Use preg_match with a regex that will extract the numbers for you. Something like this should do the trick for you:

$matches = null;
$returnValue = preg_match('/([\d+])to([\d+])/uis', 'ic3to9ltd', $matches);

After this $matches will look like:

array (
  0 => '3to9',
  1 => '3',
  2 => '9',
);

You should read somewhat on regular expressions, it's not hard to do stuff like this if you know how they work. Will make your life easier. ;-)

Answer 2

<?php

$data = <<<EOF

sure1to3
ic3to9ltd
anna1to6
joy1to4val
make6to12
ext12to36

EOF;

preg_match_all('@(\d+)to(\d+)@s', $data, $matches);
header('Content-Type: text/plain');

//print_r($matches);
foreach($matches as $match)
{
    echo sprintf("%d, %d\n", $match[1], $match[2]);
}

?>
