如何使用Regex - preg_match获取内容部分

Question

Content in the div inludes new lines, tabulators etc. and probably that's why it doesn't work:

preg_match('/<div>(.*)</div>/', $i, $matches)

I tried also preg_match('/<div>(\\n*)(.*)(\\n*)</div>/', $i, $matches)

but still doesn't work. Could you help with that?

Answer 1

Use preg_match('/<div>(.*)</div>/sm', $i, $matches) .

For details, what the additional letters mean, read documentation .

Answer 2

Add the multiline modifier ( m ) to your regex:

preg_match('/<div>(.*)</div>/m', $i, $matches);

You can read on pattern modifiers on php.net .

While this should work, please don't parse HTML with regexp. There are a lot of information to be found on this page with some searching.

Answer 3

尝试使用sm标志：

preg_match('/<div>(.*)<\/div>/sm', $i, $matches);
