php正则表达式过滤数据

Question

我只是被 php 正则表达式困住了来过滤数据。我想使用正则表达式检测“Results 1 - 20 of 60”，然后从 $content

中删除数据

$content="We have Results 1 - 20 of 60 some blah blah blah";
$content = preg_replace("/regular-expression/", " ", $content);

这里预期的输出是:We have some blah blah blah
任何想法？

Answer 1

很快，这里有一个解决方案

$content="We have Results 1 - 20 of 60 some blah blah blah";
$content = preg_replace("/(Results)(\\s+)(\\d+)(\\s+)(-)(\\s+)(\\d+)(\\s+)(of)(\\s+)(\\d+)/", " ", $content);
