[jalmz]

Hi guys,

 

I would like to ask your help on how to trim the output (title). for example the title is "php freaks rocks" it should be "php freaks..."

 

Thanks..

$title = 'PHP freaks Rocks';

$title = substr($title,0,strrpos($title,' '));

echo $title;

$title = 'PHP freaks Rocks';

$title = substr($title,0,strrpos($title,' '));

echo $title;

 

You should define what your character limit is first, so you know if the title needs chopping or not,

something like

if(strlen($title) > {
//... rest of code
}

 

or else, that code will also convert a shorter title like 'PHP freaks' into 'PHP' unnecessarily.

Thanks guys, but im comfuse on how to implement with the code above...

 

".$line["title"]."

[WebStyles]

you could create a function (so you can re-use it later on other situations)

function cutTitle($string) {
   if (strlen($string) >  {
       preg_match('/(.{' . 8 . '}.*?)\b/', $string, $matches);
       return rtrim($matches[1]) . '...';
   }
   else {
       return $str;
   }
}

 

 

then, instead of

print "<br />".$line["title"]."<br />".$line["views"]." views";

try something like

print "<br />".cutTitle($line['title'])."<br />".$line["views"]." views";

Thank you WebStyles!

 

It works like a charm.. =)
