limiting string length

[mattennant]

hello there

i'm trying to achieve that ...[read more]

type of thing

i've got a little bit of code that limits the length of a string from a column of my database. It works fine unless the string length is less than the limit i have assigned. in that instance nothing is displayed.

I'm sure it must be a simple thing i'm missing, but i'm struggling the code i'm using goes like this

[code]<? $var = $row_projects['description'];

$varlength = strlen($var);

$limit = 300;

if ($varlength > $limit) {

$var = substr($var,0,$limit);

echo $var;

}
?>[/code]

any help appreciated

try something like this:
[code]
function truncateMe($String, $limit = 300) {
  $len = strlen($String);
  if ($len > $limit) $String = substr($String, 0, $limit) . '...';
  return $String;
}

echo truncateMe($row_projects['description']);
[/code]

hope that helps

your echo statement is governed by your if statement. You should move the echo after the curly bracket which closes the if statement.
