javascript - 在 Codeigniter 中将输出限制为仅 3 行

Question

如何将内容限制为只有一定数量的字符。我想将行数限制为 3 行，每行 6 个单词，并在下一行中显示接下来的 6 个单词。 $row->openletter 给我超过 1000 个单词的完整结果。我已经在 Controller 中加载了文本助手。请找到我想要实现的附加图像。我如何限制 $row->openletter 每行只显示 6 个单词并将行数限制为 3？

<?php 	   
			echo "</li>";
		echo "</ul>"; 
	echo "</div>";
echo "</div>";
	echo "<div class='news-v2-desc'>";
		echo "<h3>";
		<a href="<?php $this->load->helper('url'); echo base_url();?>index.php/Welcome/indexes?id=<?php $data=$row->open_id; echo $data; ?>">
			<?php $ima=$row->title; echo $ima; ?>
		</a>
		<?php echo "</h3>";
		echo "<small>By Admin | California, US | In <a href='#'>Art</a></small>";
		echo "<p>";
			$string = word_limiter($row->openletter, 4);
			echo  $string;
		echo "</p>";   
	echo "</div>";
echo "</div>";
}
?>

试试这个

$para = 'Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industrys standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.';

$pos = strpos($para, ' ', 200);
echo substr($para,0,$pos )
