Question

我正在使用WordPress和WP-O-Matic自动从不同的Feed中提取内容。内容全部大写，使得WordPress博客中的帖子看起来很糟糕。我尝试使用不同的技术，但它们似乎都没有完美地工作。

以下是我尝试的一些例子：
How to uppercase the first letter in a sentence in php
How to capitalize first letter of first word in a sentence?

我目前正在使用这段代码，但它不能正常工作：

function fwisc_content($content) {
if ( is_single() ) {
global $post;
$string = get_the_content($post->ID);
$sentences = preg_split('/([.?!]+)/', $string, -1, PREG_SPLIT_NO_EMPTY|PREG_SPLIT_DELIM_CAPTURE);
$new_string = '';
foreach ($sentences as $key => $sentence) {
    $new_string .= ($key & 1) == 0?
        ucfirst(strtolower(trim($sentence))) :
        $sentence.' ';
}
return trim($new_string); 

} else { 
    return $content;
}
}
add_action( 'the_content', 'fwisc_content' );

问题是此代码删除了所有<p></p>代码，使整个帖子看起来像一个段落。

这是我需要做的事：
样本输入：

<p>THIS IS THE FIRST SENTENCE. THIS IS THE SECOND SENTENCE! THIS IS THE THIRD SENTENCE.. THIS IS THE FOURTH SENTENCE! IS THIS THE FIFTH SENTENCE?</p>
<p>THIS IS THE FIRST SENTENCE. THIS IS THE SECOND SENTENCE! THIS IS THE THIRD SENTENCE.. THIS IS THE FOURTH SENTENCE! IS THIS THE FIFTH SENTENCE?</p>

预期产出：

<p>This is the first sentence. This is the second sentence! This is the third sentence.. This is the fourth sentence! Is this the fifth sentence?</p>
<p>This is the first sentence. This is the second sentence! This is the third sentence.. This is the fourth sentence! Is this the fifth sentence?</p>

请帮忙

尝试以下代码：

<style>
    p:first-letter
    {
    text-transform: uppercase;
    }
</style>
<?php
function upperFirstWord($str) {
    return preg_replace('/([.!?])\s*(\w)/e', "strtoupper('\\1 \\2')", ucfirst(strtolower($str)));
}

echo upperFirstWord("<p>THIS IS THE FIRST SENTENCE. THIS IS THE SECOND SENTENCE! THIS IS THE THIRD SENTENCE.. THIS IS THE FOURTH SENTENCE! IS THIS THE FIFTH SENTENCE?</p><p>THIS IS THE FIRST SENTENCE. THIS IS THE SECOND SENTENCE! THIS IS THE THIRD SENTENCE.. THIS IS THE FOURTH SENTENCE! IS THIS THE FIFTH SENTENCE?</p>");
?>

希望这会有所帮助。谢谢： - ）
