No need for a regex here  if you just want to replace a piece of string by another  using str replace   should be more than enough     new   str replace        20    your string      But  if you want a bit more than that  and you probably do  if you are working with URLs  you should take a look at the urlencode   function

result   preg replace          20    your string here      you may also consider using   result   urlencode  yourstring    to escape other special characters as well

You ve got several options how to do this  either    urlencode   or rawurlencode   - functions designed to encode URLs for http protocol str replace   -  heavy machinery  string replace strtr   - would have better performance than str replace   when replacing multiple characters preg replace   use regular expressions  perl compatible    strtr    Assuming that you want to replace   t  and     with   20     replace pairs   array      t    gt    20           gt    20      return strtr   text   replace pairs    preg replace    You ve got few options here  either replacing just space      again replacing space and tab     t   or all kinds of spaces   s    return preg replace     s      20    text     Or when you need to replace string like this   t  t  t  t  with just one  20   return preg replace     s       20    text     I assumed that you really want to use manual string replacement and handle more types of whitespaces such as non breakable space   amp nbsp

Use urlencode   rather than trying to implement your own  Be lazy

I think you must use rawurlencode   instead urlencode   for your purpose   sample   image    some images jpg    url      http   example com     With urlencode  str  will result  echo  url urlencode  image     http   example com some images jpg   its not change to  20 at all  but with rawurlencode  image  will produce  echo  url rawurlencode basename  image      http   example com some 20images jpg
