function zm_get_reading_time($content) {
$zm_format = &#39;<span class="reading-time">阅读时间%min%分%sec%秒</span>&#39;;
$zm_chars_per_minute = 300; // 估算1分种阅读字数
 
$zm_format = str_replace(&#39;%num%&#39;, $zm_chars_per_minute, $zm_format);
$words = mb_strlen(preg_replace(&#39;/\s/&#39;,&#39;&#39;,html_entity_decode(strip_tags($content))),&#39;UTF-8&#39;);
 
$minutes = floor($words / $zm_chars_per_minute);
$seconds = floor($words % $zm_chars_per_minute / ($zm_chars_per_minute / 60));
return str_replace(&#39;%sec%&#39;, $seconds, str_replace(&#39;%min%&#39;, $minutes, $zm_format));

Call article word count and reading time code

Display article word count code:

<?php echo zm_count_words($text); ?>

Copy after login

Display reading time code:

<?php zm_reading_time(); ?>

Add the above calling code to the current The appropriate position of the theme body template is enough.

However, the word count and reading time are not very accurate, especially the reading time, which is even more nonsense. The default is based on the speaking speed of the CCTV announcer.

After writing this article, I found that there is a simpler code on the Internet. The difference is that the above code is accurate to seconds, and the following code only estimates to minutes.

function count_words_read_time () {
global $post;
$text_num = mb_strlen(preg_replace(&#39;/\s/&#39;,&#39;&#39;,html_entity_decode(strip_tags($post->post_content))),&#39;UTF-8&#39;);
$read_time = ceil($text_num/300); // 修改数字300调整时间
$output .= &#39;本文共计&#39; . $text_num . &#39;个字，预计阅读时长&#39; . $read_time  . &#39;分钟。&#39;;
return $output;
}
