What i would personally do is use regular expression replacement Your search regex will be as follows .{4} That will match every four characters The replacement regex will be as follows $&- That will replace each match i.e. each four characters with the match and then add a dash after On Tue, Oct 26, 2010 at 9:45 AM, julianne anyim <julia.alma@hotmail.com>wrote:

Try this.....

$orig_string = "123456789"; $insert_string = "-"; $position = "4"; $newstring=substr_replace($orig_string, $insert_string, $position, 0); echo $newstring;

Anyone got an idea of an internal PHP function that would enable me to insert a symbol e.g. '-' after every 4 characters in a String? e.g. 12345678 becomes 1234-5678.

+1 for regex $str = "12345678901234567890"; echo trim(preg_replace("/(.{4})/", "\\1-", $str), "-"); On 10/26/2010 10:03 AM, Rad! wrote:
