php search and replace but not duplicate.

Question

I want to replace the word "Dozenten" with "Dozentin" and the word "Dozent" with "Dozenten" using PHP. The problem is, "Dozent" appears in both words. I can't continue using `str_replace`. How to avoid getting results similar to "Dozentenin"?

Answer 1

你可以使用`strtr`函数来实现，它可以在字符串中进行子字符串的翻译（替换）：

<?php 
$s = "Dozenten Dozent Dozent Dozenten"; 
echo strtr($s, array("Dozenten" > "Dozentin", "Dozent" => "Dozenten"));
