How to do replace multiple times ? php

I want to replace word1 with word2 and word2 with word1 for this string :

word1 word2

here is what i want to do :

1.replace word1 with word2 => I get : word2 word2

2.replace word2 with word1 => I should get word2 word1 .

but I get this : word1 word1 becuase str_replace function also replace the first replaced word1.

How to avoid this kind of problems ?

thanks

You can't achieve this by str_replace. Use string translation (strtr) which was designed to do so instead:

$words = 'word1 word2';
$wordsReplaced = strtr($words, [
    'word1' => 'word2',
    'word2' => 'word1'
]);
