Limiting the amount of characters in a string

Question

I'm using the following to limit the amount of characters in a string

<?php $eventtitle1 = get_the_title();
$eventtitle1_str = strip_tags($eventtitle1, '');
echo substr($eventtitle1_str,0,30) . "…"; ?>

Is it possible to add the "..." if the string is more than 30 characters but not add it if it's less?

e.g

So it does this for a longer title:

"This is a longer ti..."

And it does this for a shorter title:

"This is a title"

(i.e not this - "This is a title ...")

Just check the length of the string before you shorten it. If it is more than 30 characters, trim and add the ellipsis. If not, do nothing. You need an `if` statement for that: http://php.net/manual/en/control-structures.if.php — Felix Kling, May 11 '12 at 08:41

public function Truncate($string, $maxLen)
{
    if (strlen($string) > $maxLen)
    {
        return substr($string, 0, $maxLen) . '...';
    }
    return $string;
}

Try this

<?php $eventtitle1 = get_the_title();
    $eventtitle1_str = strip_tags($eventtitle1, '');
    $strlen= strlen ( $eventtitle1_stng );
    if($strlen>30)
    echo substr($eventtitle1_str,0,30) . "…";
    else
    echo $eventtitle1_str;
     ?>

Should probably use `…` instead of `…` – Nick May 11 '12 at 09:22

Try this:

if (strlen($eventtitle1_str) > 30) {
    $eventtitle1_str  = substr($eventtitle1_str,0,30) . "…";

See strlen.

For example:

echo substr($eventtitle1_str,0,30) . (strlen($eventtitle1_str) > 30 ? "…" : "");

You can use strlen for check number of characters.

<?php $eventtitle1 = get_the_title();
    $eventtitle1_str = strip_tags($eventtitle1, '');
     if(strlen($eventtitle1_str) > 30 ){     
       echo substr($eventtitle1_str,0,30) . "…"; 
    }else{
       echo substr($eventtitle1_str,0,30); 
     }

 ?>

thanks

<?php

if (strlen($eventtitle1_str) > 30) {
    echo substr($eventtitle1_str, 0, 30)."…";
} else {
    echo $eventtitle1_str;

Besides the many right answers here I also recommend using the … entity in HTML instead of ... and also the MBSTRING extension.

So the code would look like:

$eventtitle1 = get_the_title();
$eventtitle1_str = strip_tags($eventtitle1, '');
if(mb_strlen($eventtitle1_str) > 30)
    echo mb_substr($eventtitle1_str, 0, 30) . "&hellip;";
} else {
    echo $eventtitle1_str;
}

@FelixKling Had it written as comment then decided to make it an answer... Is it this bad? Have no problem turning it into comment to the OP... – shadyyx May 11 '12 at 08:48
It's just not answering the question at hand, it's more like additional information, *in my opinion*. Others might think differently... do what you feel most comfortable with :) – Felix Kling May 11 '12 at 08:51

I think its a Job for str_word_count http://php.net/manual/en/function.str-word-count.php

Example

$test = " I love to play foodtball";
var_dump ( substr ( $test, 0, 12 ) );
var_dump ( wordCount ( $test, 12 ) );

Output

string ' I love to p' (length=12)
string 'I love to play ...' (length=18)

Can you see one is more readable than the other

Function Used

function wordCount($str, $max, $surffix = "...") {
    $total = 0;
    $words = str_word_count ( $str, 1 );
    $output = "";
    foreach ( $words as $word ) {
        $total += strlen ( $word );
        if ($max < $total)
            break;
        $output .= $word . " ";
    }
    $output .= $surffix ;
    return trim ( $output );
}
