php - 如何从段落外删除分隔符

Question

我想删除所有 <br> <p></p> 之外的标签.但是在<p></p>里面休息不应该受到伤害。我怎样才能在 php 中实现这个。下面是一个例子。

$html = "<br> <p> This is the Firs para <br> 
        This is a line after the first break <br>
        This is the line after the 2nd break <br>
        Here the first para ends </p>
        <br>
        <br>
        <p> This is the 2nd para <br> 
        This is a line after the first break in 2nd para <br>
        This is the line after the 2nd break <br>
        Here the 2nd para ends </p>"

我想要的结果如下

$html = "<p> This is the Firs para <br> 
        This is a line after the first break <br>
        This is the line after the 2nd break <br>
        Here the first para ends </p>
        <p> This is the 2nd para <br> 
        This is a line after the first break in 2nd para <br>
        This is the line after the 2nd break <br>
        Here the 2nd para ends </p>"

这对你有帮助。

$out = preg_replace("(<p(?:\s+\w+(?:=\w+|\"[^\"]+\"|'[^']+')?)*>.*?</p>(*SKIP)(*FAIL)"
."|<br>)is", "", $html);

echo $out;
