在php中生成代码片段

Question

我有一长段从搜索查询中回来的文本。 我想显示文本的片段，而不是整个内容，并突出显示片段中的搜索查询。 我意识到决定要分片的文本的哪一部分可能会变得复杂，并且我希望得到关于如何做到这一点的任何想法？

谢谢！

例如

$text = " 
I have a long chunk of text that came back from a search query. I'd like to display a 
snippet of the text, not the entire thing, and highlight the search query within the 
snippet. I realize that decided what part of the text to slice can be complicated, and 
I was hoping for any ideas on how do to this? 
"; 

$query = "the text"; 

preg_match("~\b.{0,20}$query.{0,20}\b~", $text, $m); 
echo str_replace($query, "<strong>$query</strong>", $m[0]);
