Notice: Undefined Offset

[FUNKAM35]

Hi, I am getting a

: Undefined offset

 

with the following code

 

$words=str_word_count($desc);
if($words >25)
{
$offset = strpos ($desc, " " ,170);
$desc = substr ($desc,0,$offset);
$desc.= "......";
}

 

I only want to display a certain length of the desc which works but I get this error message, any ideas welcome

thanks Notice

25 words does not guarantee there will be 170 characters. strpos is returning false; therefore, $offset is not an acceptable argument for substr().

thanksmrmarcus, so how do I fix this?

If 170 is the limit before truncation, then skip the words check and just do a character count:

 

$count = strlen($desc);
$max = 170;
if ($count > $max) {
   $desc = substr($desc, 0, $max);
   $desc .= '......';
}
echo $desc;
