Even better would be to create your own method that does just that, similar to... .
Your best best is to loop through an array of strings and call Replace during each iteration, generally speaking that is what other functions will do under the hood.

I am trying to achieve the following:
$subject = 'a b a';
$search = 'a';
$replace = '1';
Desired result:
Array
(
[0] => 1 b a
[1] => a b 1

preg_replace('/\b'.$search.'(?=\s+|$)/u', $replace...

Convert it to set , that's the easiest way to get rid of duplicates .

I recently read the questions that recommend against using switch-case statements in languages that do support it. As far as Python goes, I've seen a number of switch case replacements, such as:
