[SOLVED] MAX x CHARS ... on search form?

[Northern Flame]

I have a search form which works fine,

when a user searches for something it displays

the results in this format

 

TITLE

DESCRIPTION

LINK(click here to read more)

 

but sometimes the description is too long and it stretches

out my template, how can I set the limit for the maximum

amount of characters allowed to be displayed from my

description and after the maximum characters echo "..."?

[Daniel0]

Something like this?

 

<?php
function truncate($string, $max_chars = 30)
{
if(strlen($string) > $max_chars)
{
	$string = substr($string, 0, $max_chars).'...';
}

return $string;
}

echo truncate(str_repeat('abc', 20));
?>

thanks Daniel0 

 

I just tested it out,

but it works better if you replace the 20 with 1

 

<?php
function truncate($string, $max_chars = 30)
{
if(strlen($string) > $max_chars)
{
	$string = substr($string, 0, $max_chars).'...';
}

return $string;
}

echo truncate(str_repeat('abc', 1));
?>

this way it doesnt repeat my text 20 times lol

The str_repeat() was just to get a string long enough to be truncated. I just didn't bother to to type a lot of characters so I had PHP do it for me.

 

You'd just use it like this:

truncate('long text here')
