PHP limit characters in string

[andretanguy]

Hey there!

 

ok so at the moment i do this: <?php echo $row['short_desc']; ?>...

but i want to limit the output of short_desc to 300 chars.

 

i came across this:

 

<?php function truncate_string($string, $max_length){

    if (strlen($string) > $max_length) {

        $string = substr($string,0,$max_length);

        $string .= '..';

    }

return $string;

}?>

 

i need some help turning $string into my short_desc - if someone can help that'd be awesome

 

cheers

<?php echo truncate_string($row['short_desc'], 300); ?>

 

will only print out the first 300 characters with an appended .. on the end

its generating a load of errors - is there another solution?

[andretanguy]

it works like this:

 

<?php echo substr($row['short_desc'], 0, 130); ?>...

 

hope it helps someone else

 

cheers

function trunc($details,$max) {

if(strlen($details)>$max) {

        $details = substr($details,0,$max);

        $i = strrpos($details," ");

        $details = substr($details,0,$i);

        $details = $details."...";

    }

    return $details;

}

 

echo trunc($row['short_desc']);

you forgot to pass it the $max should it be

echo trunc($row['short_desc'],300);
