Let's say i have the string $urlname = "pine-tree-tshirt--green-xs"

I want my result to be $urlname = "pine-tree-tshirt-green-xs"

I don't want to remove all duplicates characters (for example tree, the e should be duplicated here), only the - character.

`str_replace("--","-",$urlname);` – Jeff Dec 19 '18 at 10:44
@MasivuyeCokile thanks, it is a duplicate, and I found there the answer $characterwanted = array("-"); $expression = join('|', $characterwanted); $result = preg_replace('/(' . $expression . ')\1+/', '$1', $urlname); – Raluca Albu Dec 19 '18 at 10:59
