PHP string replace match whole word

What I want to do is to replace Tomato with Apple for example. The Probleim I'm running in is:

when the string contains "Tomatos" (mention the s) it will replace Tomato and leafe me with a string "Apples" (again mention the s).

Because "Tomato" != "Tomatos" (...s) it shall NOT replace.

Which PHP funktion is good for this task? I tried the str_replace function but it seems like it isn't possible to archive my task with it.

The words are seperated with ",".

preg_replace. You can search for a regular expression, like \bTomato\b, which means whole word Tomato.

If you want to use str_replace try adding commas either side of the Tomato. Then it should only replace the word Tomato.

Otherwise you'll need preg_replace
