Ucfirst <strong>标记</strong>中的所有字符串

Question

我正在尝试在<strong>中找到句子中的所有字符串。没有任何运气试了这个：

 function getTextBetweenTags($string, $tagname)
 {
    $pattern = "/<$tagname>(.*?)<\/$tagname>/";
    preg_match($pattern, $string, $matches);
    return ucfirst($matches[1]);
 }

$sentence = "Yellow pitty lies <strong>about</strong> the life.";

$finalsentence = getTextBetweenTags($sentence,"strong");

这样做的正确方法是什么？

Answer 1

有一种更简单的方法。而不是使用PHP，你只能使用css，例如：

strong:first-letter{
    text-transform: capitalize
}

Answer 2

您需要在标记之前和之后包含匹配文字。

function getTextBetweenTags($string, $tagname)
 {
    $pattern = "/(.*<$tagname>)(.*?)(<\/$tagname>.*)/";
    preg_match($pattern, $string, $matches);
    return $matches[1] . ucfirst($matches[2]) . $matches[3];
 }

$sentence = "Yellow pitty lies <strong>about</strong> the life.";

$finalsentence = getTextBetweenTags($sentence,"strong");
