将这两个正则表达式合并为一个[关闭]

Question

I feel like I can learn a lot by seeing these two regular expressions as one. Mainly selecting the space in between > and < while not selecting the > and < themselves, so I can replace it with "" rather than "><". Is there a way that these could be merged without selecting that space?

    $html = preg_replace('/(
)|()/',"",$html);
    $html = preg_replace('/>(\s+)</',"><",$html);

Answer 1

$html = preg_replace('/[
]+|(?<=>)\s+(?=<)/',"",$html);
