删除字符串中特定开头的单词

Question

$string = '@English is a West Germanic @language that was first spoken in early medieval @England and is now a global lingua franca. @It is spoken as a first language by the';

我如何删除以“在一个动作中”开头的所有单词？

链接str_replace()的东西呢？

`$result = 'is a West Germanic that was first spoken in early medieval and is now a global lingua franca. is spoken as a first language by the'`;

Answer 1

给你：

echo $string | sed -e 's/@\w*//g'

这将与regex @\w*匹配的所有子字符串替换为空字符串。G标志确保匹配多个字符串。
