我需要使用preg_replace或其他方式替换以'Title:'开始并以'Article Body:'结束的文本。替换后的文本将不包含上面的引号。
,
标题:示例文本1
身体条
示例文本2
应该只输出
示例文本2
如何在php中做到这一点?
使用正反头。
$result = preg_replace('/(?<=Title:).*(?=Article Body:)/s', ''nTest'n', $subject);
上面的正则表达式将替换Title:…文章正文:with 'nTest'n
说明:
"
(?<= # Assert that the regex below can be matched, with the match ending at this position (positive lookbehind)
Title: # Match the characters “Title:” literally
)
. # Match any single character
* # Between zero and unlimited times, as many times as possible, giving back as needed (greedy)
(?= # Assert that the regex below can be matched, starting at this position (positive lookahead)
Article' Body: # Match the characters “Article Body:” literally
)
"
$str = 'Title: this is sample text Article Body: this is also sample text';
// output: this is sample text this is also sample text
echo preg_replace('~Title: (.*)Article Body: (.*)~', '$1 $2', $str);
正则表达式非常有用，你应该学会如何使用它。网上有很多文章，也是这个总结我可以帮你。
