note 86254 added to function.substr-replace

The preemptive test to see if $string is "too long" shouldn't add strlen($replacement) to $max.  $max should represent the absolute maximum length of string returned.  The size of the $replacement is irrelevant in that determination.

The rest of the function (unchanged below) operates as defined above.  Meaning, the size of the $replacement is subtracted from the $max, so that the returned string is exactly the length of $max.

<?php
function truncate($string, $max = 20, $replacement = '')
{
    if (strlen($string) <= $max)
    {
        return $string;
    }
    $leave = $max - strlen ($replacement);
    return substr_replace($string, $replacement, $leave);
}
?>
