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';

如何在一次操作中删除所有以@开头的单词？

linke str_replace()怎么样？

`$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

你走了：

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

这将使用空字符串替换与正则表达式@ \ w *匹配的所有子字符串。 g标志确保匹配多个字符串。
