显示帖子摘录，受字数限制

Question

I am working on my php website (Not a Wordpress site) on the main index I display the two newest post. The thing is on the description it shows the entire article I find myself needing to display post excerpts maybe 35 word limit.

<?=$line["m_description"]?>

<?
$qresult3 = mysql_query("SELECT * FROM t_users WHERE u_id=".$line["m_userid"]." LIMIT 1");
if (mysql_num_rows($qresult3)<1) { ?>

Answer 1

I have a function though other people may say it's not good because I'm still good at PHP too (tips welcome people) but this will give you what you are looking for, it may need better coding if anyone has suggestions.

function Short($text, $length, $url, $more){
$short = mb_substr($text, 0, $length);

if($short != $text) {
    $lastspace = strrpos($short, ' ');
    $short = substr($short , 0, $lastspace);

    if(!$more){
        $more = "Read Full Post";
    } // end if more is blank

    $short .= "...[<a href='$url'>$more</a>]";
} // end if content != short

$short = str_replace("’","'", $short);
$short = stripslashes($short);
$short = nl2br($short);

} // end short function

To Use:

say your article content is the variable $content

function($content, "35", "http://domain.com/article_post", "Read Full Story");
echo $short;

Similarly, you can adjust the function to remove $url and $more from it and just have the excerpt with ... at the end.
