php正则表达式来过滤数据

Question

我只是陷入了使用php正则表达式来过滤数据。我想使用正则表达式检测“结果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);

此处预期输出为：We have some blah blah blah
任何想法？

Answer 1

很快，这是一个解决方案

$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);

Answer 2

您可以使用此正则表达式

 $content = preg_replace("/\s*results\s+\d+\s+-\s+\d+\s+of\s+\d+\s*/i", " ", $content);

删除Results 1 - 20 of 60。

Answer 3

您可以通过

执行此操作

<?php
    $str="We have Results 1 - 20 of 60 some blah blah blah";
    echo preg_replace("/(Results)(\\s+)(\\d+)(\\s+)(-)(\\s+)(\\d+)(\\s+)(of)(\\s+)(\\d+)/", " ", $str);
?>

<强>输出

We have some blah blah blah
