如何从MySQL等数据库中读取部分html编码文章？

I am trying to write a blog system. The main page is consist of part of the content of blog entries.

The problem is how could I make sure the excerpt is truncated correctly, since the blog entries is stored in HTML code.

Thanks.

Your best bet would be to use strip_tags() to remove the HTML from it and show only the first 300 or so characters using substr. Otherwise you'd have to parse the HTML to break it at an appropriate place so as not to break the rest of your layout.

strip_tags() and wordwrap()

<?php
$blog_entry = '<div class="myclass"><p><h1>I am trying to write a blog system.</h1> The main page is consist of part of the content of blog entries.</p>    
<p>The problem is how could I make sure the excerpt is truncated correctly, since the blog entries is stored in HTML code.</p>
<p>Thanks.</p></div>';

// Allow a couple of tags (<p>,<a>), or don't - wrap excerpts into your own CSS class in your UI

$thisExcerpt = wordwrap(strip_tags($blog_entry, '<p>,<a>'),50);
$thisExcerpt = explode("
", $thisExcerpt);
$thisExcerpt = $thisExcerpt[0];

echo $thisExcerpt . '...';
?>
