Remove whitespace around certain character with preg_replace

I have a string where I want to remove all the whitespace around a certain character using preg_replace. In my case this character is /.

For example:

first part / second part would become first part/second part

Or let's say that character is : now:

first part : second part would become first part:second part

I couldn't find an example on how to do this... Thanks!

match optional space followed by your character (captured in brackets) followed by another optional space and then replace by your captured character

preg_replace('/\s*(:)\s*/',"$1",$str);

Replace : with your character.

$string = preg_replace("/\s*:\s*/", ":", $string);

In english:

Replace any amount of whitespace (including 0), then a : and then any amount of whitespace again, by just a :.

$string = preg_replace("/\s*([\/:])\s*/", "$1", $string);

Explanation:

  • \s* means any amount (*) of whitespace (\s)
  • [\/:] is either a / or a :. If you want another character, just add it here.
  • the brackets are a capture group which you reference with the $1 meaning that if it matches a : then the $1 will mean :.
