Technique #1: Simple

function myTruncate($string, $limit, $break=".", $pad="...") {
        if(strlen($string) <= $limit) return $string; 
        if(false !== ($breakpoint = strpos($string, $break, $limit))) { 
            if($breakpoint < strlen($string) - 1) { 
                $string = substr($string, 0, $breakpoint) . $pad; } 
            } return $string; 
}

function get_suffix($number) {

   $last_number = substr($number,-1); //fetch the last number

   if($last_number == "0" || $last_number == 0){ $last_number = 4; } // if last number is 0 than it assign value 4
      return date("S",mktime(0,0,0,1,$last_number,2009));
}

Returns suffix of any number:…

$(function(){
       $("a").each(function(){
               if ($(this).attr("href") == window.location.pathname){
                       $(this).addClass("selected");
               }
       });
});

This function will add the class “selected” to any links (even relative) that point to the current page.…

$string = eregi_replace('([_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3})','<a href="mailto:\\1">\\1</a>', $text);
echo $string;

Add to functions.php file

remove_filter('the_content', 'wptexturize');
remove_filter('the_excerpt', 'wptexturize');
remove_filter('comment_text', 'wptexturize');
remove_filter('the_title', 'wptexturize');

the wptexturize function is responsible for lots of automatic alterations to text stored in WordPress like automatic elipses (…), em and en dashes, typographers quotes, etc.…

Include Basic WordPress Functions

<?php
  // Include WordPress
  define('WP_USE_THEMES', false);
  require('/server/path/to/your/wordpress/site/htdocs/blog/wp-blog-header.php');
  query_posts('showposts=1');
?>

Run Loop

<?php while (have_posts()): the_post(); ?>
   <h2><?php the_title(); ?></h2>
   <?php the_excerpt(); ?>
   <p><a href="<?php the_permalink(); ?>" class="red">Read more...</a></p>
<?php endwhile; ?>

This can be used on …

function getQueryVariable(variable)
{
       var query = window.location.search.substring(1);
       var vars = query.split("&");
       for (var i=0;i<vars.length;i++) {
               var pair = vars[i].split("=");
               if(pair[0] == variable){return pair[1];}
       }
       return(false);
}

Example URL:
http://www.example.com/index.php?id=1&image=awesome.jpg

Calling getQueryVariable("id") – would return “1”.
Calling getQueryVariable("image") – would …

a {
  background: url(sprite.png) no-repeat;
  display: block;
  height: 30px;
  width: 250px;
}

a:hover {
  background-position: 0 -30px;
}

The set height and width ensure only a portion of the sprite.png graphic is shown. The rollover shifts the position of the …

       $rec = $row[$y];
       return $rec;
}
