在字符串的开头标识HTML标记并将其删除

Question

I want to get html tag in string at starting position and remove it from the string

my demo strings are below:

<I>little willingness</I> that, as the Course itself was to emphasise

this will return <I> tag as o/p

<p>little willingness</p> that, as the Course itself was to emphasise

this will return <p> tag as o/p

little willingness that, <p>as the Course itself was to emphasise</p>

this will return me null as o/p

How do I modify my code below to check only for HTML tags at the start of the line and then remove them?

preg_match("/<[^<]+>/",$string,$m);

Answer 1

First Step:

$paragraph = "<p><i>Please don't</i> blow me to pieces. How to put span here.</p>";
$sentences = explode(".", $paragraph);

Next, add span tags to each sentence:

foreach($sentences as &$sentence) {
    $sentence = "<span>$sentence</span>";
}

Finally, re-implode them into a paragraph:

$paragraph = implode(".", $sentences);
