推荐答案

在PHP中：

ECHO str_replace(': ', ': <br>', 'PHP Reference: Beginner to Intermediate PHP 5');

将是一种方法。



你的例子将取代所有''你的所有单词都在一个列表中，每行一个单词。在进行更换时，确保正确且唯一地确定目标非常重要。通常没有单一的刺痛和替换通常是其目标及其修改。



有时您会替换搜索字符串中的所有字符，有时您不会。



这是很多解析问题的关键。 &NBSP;当他们变得艰难的时候会有RegEx，这本身就是一种特殊技能。

would be one way to do it.

Your example would replace all ' ' and you'd have all of your words in a single list, one word per row. When doing a replace it is important to make sure you have correctly and uniquely determined your target. Often not a single sting and replace is often that target with its modifications.

Sometimes you replace all the chars in the search string and sometimes you don't.

That's the key to a lot of parsing problems.   And when they get tough there's RegEx, which in and of itself is a special skill.
