Truncate Long String Exactly In Middle | CSS-Tricks

Code Snippets → PHP → Truncate Long String Exactly In Middle

Chris Coyier on Oct 21, 2009 (Updated on Jan 8, 2010)

This will truncate a longer string to a smaller string of specified length (e.g. the “25” value in the code below) while replacing the middle portion with a separator exactly in the middle. Useful when you need to truncate a string but still show the beginning (e.g. for sorting and because it is most recognizable) and also show the end (perhaps to show a file name).

<?php

$longString = 'abcdefghijklmnopqrstuvwxyz0123456789z.jpg';
$separator = '/.../';
$separatorlength = strlen($separator) ;
$maxlength = 25 - $separatorlength;
$start = $maxlength / 2 ;
$trunc =  strlen($longString) - $maxlength;

echo substr_replace($longString, $separator, $start, $trunc);

//prints "abcdefghij/.../56789z.jpg"

?>

Nice, thanks!

Here’s my code for links (copy):


 $max)
        $title = substr_replace($title, '…', $max/2, round(-$max/2));
    $icon = "";
    $link = "$icon $title";
    return $link;
}
echo beatufy_url('http://en.wikipedia.org/wiki/World_Bank_Governance_Surveys');
?>

I expected this behavior from your parser so you can ignore the code and open the link ;)

Handy PHP function:

function truncate_middle($text, $length = 24, $separator = '...')
{
  if(strlen($text) <= $length)
  {
    return $text;
  }

  $length = ($length - strlen($separator)) / 2;
  return substr_replace($text, $separator, $length, -$length);
}
