First, it looks as if the [1] element of your array contains the values you
want. So, why not do something like:
$string = '245/45ZR17';
$tiresizearray = preg_match_all('/(?<digit>\d+)/', $string, $ptiresize);
$newsize = join("", $ptiresize[1]);
I can't get your regex to work. I don't know how the <digit> will work in the
regex. However, if you can get the array generated then my code should work.
By the way, it looks as if you are merely trying to get rid of characters which
are not numbers. If they always followed the pattern you gave, you could use:
$string = '245/45ZR17';
$newsize = str_replace(array(' ','/','R','Z'), "", $string);
What do all of those numbers mean in tire sizes anyways?
