Only display a certain number of chars? (and other problems)

Ok, I am working on making a news script for a new site... I have currently come up with these problems:

I want to show a snippet of the news post on the main page, but how can i restrict the number of characters that are displayed?

For example - "Yadda Yadda has died today after an assasination in his home..."

I only want it to display a certain number of characters or words, or whatever I can restrict! Can anyone help me with that?

Also...

Can anyone tell me an effective way to have user comments on news posts, I thought of having a table called "comments" and then a "postid" field... and then displaying all the comments where the postid=1 or whatever, but how do I set postid from one table and then read it in another?

Please help me in as plain-english as possible, I havent been into this PHP stuff too long, I have made some scripts though, so I know a fair bit.

Thanks for your time!

Here's the query I have at the moment:

PHP Code:


		
			


<?



$sqlhostname = "localhost";

$login = "******";

$password = "******";

$base = "******";



$db_connect = mysql_connect($sqlhostname,$login,$password);

$base_selection = mysql_select_db($base,$db_connect);



$query = "SELECT * FROM gaming_news ORDER BY id  ASC  LIMIT 0,1";

$req = mysql_query($query);



if (!$req)

{ echo "<B>Error ".mysql_errno()." :</B> ".mysql_error()."";

exit; }

$res = mysql_num_rows($req);



if ($res == 0)

   { echo "<center><b>Sorry there is no result.</b></center>";}

else 

   { while($row = mysql_fetch_array($req))

            {

               extract($row);



                      echo"<img src=\"images/newslatest.gif\" align=\"left\"><b>$headline</b> posted by: <b>$author</b> - $story_text... <br>[<b>read full story</b>]



";

    }

mysql_free_result($req);

}



?>

I'll be wanting to limit $story_text

Hope that helps you to help me! :)

For this use the SUBSTR() function like so...

PHP Code:


		
			
echo substr($MY_SNIPPET,0,100);

this would show the first 100 characters in that snippet.

I've adjusted your code to spit out the first 100 chars. Look at the line where $story_text is located. Notice $story_text has now become ".substr($story_text,0,100)."

Hope that helps :)

PHP Code:


		
			
<?



$sqlhostname = "localhost";

$login = "******";

$password = "******";

$base = "******";



$db_connect = mysql_connect($sqlhostname,$login,$password);

$base_selection = mysql_select_db($base,$db_connect);



$query = "SELECT * FROM gaming_news ORDER BY id  ASC  LIMIT 0,1";

$req = mysql_query($query);



if (!$req)

{ echo "<B>Error ".mysql_errno()." :</B> ".mysql_error()."";

exit; }

$res = mysql_num_rows($req);



if ($res == 0)

   { echo "<center><b>Sorry there is no result.</b></center>";}

else 

   { while($row = mysql_fetch_array($req))

            {

               extract($row);



                      echo"<img src=\"images/newslatest.gif\" align=\"left\"><b>$headline</b> posted by: <b>$author</b> - ".substr($story_text,0,100)."... <br>[<b>read full story</b>]



";

    }

mysql_free_result($req);

}



?>
