  好吧，首先找到第一个点的位置 . 然后读取包括点的字符串 .

  $lorem  = 'Lorem ipsum dolor sit amet...';
  $dotpos = strpos($lorem, '.');
  $phrase = substr($lorem, 0, $dotpos + 1);

  在PHP中使用 substr() 和 strpos()

  <?php
  $string = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.";
  echo (substr($string,0,strpos($string,'.')+1));

  你需要爆炸它：http://php.net/manual/en/function.explode.php

  $firstSentence = explode(".", $string, 2);
  echo $firstSentence[0] . ".";
  

  编辑以将 . 添加到echo的结尾 .
