wordpress如何获取文章字数和计算阅读时间

wordpress如何获取文章字数和阅读时间，下面web建站小编给大家详细介绍一下如何实现代码！

找到当前主题函数模板functions.php中添加以下代码：

1、获取文章字数

// 字数统计
function get_words_count($text) {
  global $post;
  if ( '' == $text ) {
  $text = $post->post_content;
  if (mb_strlen($output, 'UTF-8') < mb_strlen($text, 'UTF-8')) $output .= '<span class="word-count">共' . 
   mb_strlen(preg_replace('/\s/','',html_entity_decode(strip_tags($post->post_content))),'UTF-8') .'字 
   </span>';
  return $output;
  }
}

模板中调用文章字数

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

2、获取文章阅读时间

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

function get_reading_time() {
  echo zm_get_reading_time(get_the_content());
}

模板中调用文章阅读时间

<?php get_reading_time(); ?>

3、文章字数和文章阅读时间一起显示

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

模板中调用
