Well you should just change the name of $text to like $Text, That might fix the problem [img src=\"style_emoticons/[#EMO_DIR#]/smile.gif\" style=\"vertical-align:middle\" emoid=\":smile:\" border=\"0\" alt=\"smile.gif\" /]

Hmm no that doesn't do anything.. I've actually found that script elsewhere on the internet and it is exactly the same as the one I have so I think that should be right. Thanks though

[code]
$text = $text." ";
$text = substr($text,0,$chars);
$text = substr($text,0,strrpos($text,' '));
$text = $text." <strong>...</strong> ";
[/code]
You use $text as a varible in the function twice

Would that not make it display the result though. I know zilch about php [img src=\"style_emoticons/[#EMO_DIR#]/huh.gif\" style=\"vertical-align:middle\" emoid=\":huh:\" border=\"0\" alt=\"huh.gif\" /] , which line should i change.

Ugh I'm going nuts. I've located some code that repeats itself but I don't think that's causing the problem. There is a tag that says unfinished code so I'm assuming something there is off.

[PHP code with a bug]

I'm sorry this might be pretty basic to you guys. But i need to fix this code by tomorrow and i have no clue how to do it. It was written by somebody else and I'm not very well versed in PHP. It is supposed to pull an article from a database (image and some text i believe) truncate it into a kind of a blog format and print the result to the screen. When I run it though i get an empty screen. If somebody could help I'd really appreciate it

<?php

// Function to truncate long text

function ShortenText($text) {

// Change to the number of characters you want to display
$chars = 1000;

$text = $text." ";
$text = substr($text,0,$chars);
$text = substr($text,0,strrpos($text,' '));
$text = $text." <strong>...</strong> ";

return $text;

}

// Function to close all HTML tags
function close_tags($string)
{
// match opened tags
if(preg_match_all('/<([a-z]+)[ >]/', $string, $start_tags))
{
$start_tags = $start_tags[1];

// match closed tags
if(preg_match_all('/<\/([a-z]+)>/', $string, $end_tags))
{
$complete_tags = array();
$end_tags = $end_tags[1];

foreach($start_tags as $key => $val)
{
$posb = array_search($val, $end_tags);
if(is_integer($posb))
{
unset($end_tags[$posb]);
}
else
{
$complete_tags[] = $val;
}
}
}

{
$complete_tags = $start_tags;

$complete_tags = array_reverse($complete_tags);
for($i = 0; $i < count($complete_tags); $i++)

$string .= '</' . $complete_tags[$i] . '>';
