Of course to target and replace just the dash you could use
preg_replace('/([0-9]+)(-)([0-9]+)/', '$1dash$3', '47-73');
where the word 'dash' is your replacement dash naturally :)
Just to 'splain that a little ...
$string = '47-73';
$pattern = '/([0-9]+)(-)([0-9]+)/';
$replacement = '$1dash$3';
$new_string = preg_replace($pattern, $replacement, $string);
There are three sets of parens in the pattern. They get numbered left to
right $1, $2, $3. In the replacement string $1 and $3 are left alone and
the $2 is replaced by 'dash'.
Another way to write the replacement string that maybe makes this
clearer is
$replacement = '${1}dash${3}'
