正则表达式以字符替换结束

Question

任何人都可以解决此正则表达式吗？

• 查找所有以（,PE开头和（,）结尾的字符串
• 如何替换BEGIN（,'PE）和END（',），并保持MIDDLE（* unknown words here *）？
• 因此，上面的示例将以,PE unknown words here,开始并以,'PE unknown words here',结束

有人知道正则表达式的学习资源，以便我自己解决此类问题吗？

• 我有一位同事向我展示了此网站（https://www.whatsmyip.org/regular-expression-tester/）。包括测试窗口和备忘单参考卡。
