Savride’s Weblog

Another simple function of my library (extended at 09-09-2008).

Use it when You need to cut some text/string to given length in chars or specified word count and wish to add some suffix at the end like » read more or …

From:

$_str = “Here’s a sampling of features that might make you want to use WordPress.com. (Besides it being run by some swell folks!) We’re not fancy-pants marketers“

$_str = _str_cut( $_str, 30, “ » read more”);

 To:

Here’s a sampling of features » read more 

/**
 * (C)2008 savride.wordpress.com
 * @return String cut to needed length and with suffix if need one
 * for example "..." as default or "<a href=" or what you just enter
 * @param $_str Object given string
 * @param $_len Object new length to set
 * @param $_more Object[optional] suffix string instead of "..." fe. <a href="http://set_some.link.com">Link name set</a>
  * @param $_cnt_words - cut to given words NUM - UPDATE
 */

function _str_cut( $_str, $_len, $_more = " ...", $_cnt_words = false, $_separator = " ")
{
  $_str = strip_tags( $_str );

  // return by WORD COUNT - update
  if( $_cnt_words )
  {
  $_new_str = "";

  if( $_cnt_words == 1)
    return strtok( $_str, $_separator );

    $_new_str .= $_separator.strtok( $_str, $_separator );

    while( $_cnt_words > 0 )
     {
     $_new_str .= $_separator.strtok( $_separator );
     $_cnt_words--;
     }
   return trim($_new_str, $_separator);
  }
  // return by WORD COUNT - update

  $_start_len = strlen( $_str);
  $_new_len   = $_len - strlen( strip_tags($_more)); 
 
  if ( $_start_len >= $_new_len)
    {
    $_str = substr( $_str, 0, $_new_len);
    $_str = preg_replace( '/\s+[^\s]+?$/', "", $_str);
    $_str .= " ".$_more;
    }
 
  return( $_str);
}

Feel free to use it.
