英文:
phpsearch and replace but not duplicate
问题
我想使用PHP将单词“Dozenten”替换为“Dozentin”，将单词“Dozent”替换为“Dozenten”。现在的问题是，“Dozent”在两个单词中都出现了。我无法使用str_replace进一步处理。如何防止出现类似“Dozentenin”的情况？
英文:
I would like to use php to replace the word "Dozenten" with "Dozentin" and the word "Dozent" with "Dozenten". The problem now is that "Dozent" occurs in both words. I can't get any further with a str_replace. How can I prevent that I then get something like "Dozentenin"?

你可以使用strtr函数，这将翻译（替换）字符串中的子字符串：
<?php
$s = "Dozenten Dozent Dozent Dozenten";
echo strtr($s, array("Dozenten" => "Dozentin", "Dozent" => "Dozenten"));
英文:
You can make use of the strtr function, this will translate (replace) substrings in your string:
<?php
$s = "Dozenten Dozent Dozent Dozenten";
echo strtr($s, array("Dozenten" => "Dozentin", "Dozent" => "Dozenten"));
