Intro

OOP is a great concept, it simplifies the programmer’s life, especially in the field of interface development. Nearly all modern web-interfaces use JS in some way – for field highlighting, validation, help etc. It’s OK when there are such simple things.
And now imagine, that we have a set of dialogue windows (HTML+CSS) for adding a comment, rating, sending to the friend. Each of these boxes has a number of functions – check if user is logged in(if not – show login form), send AJAX request, process response, show error/success messages, position the box on the page etc.

Recently I’ve learned one nice trick with for loop. When you use it, you should know he number of itereations. Most people do it like this:

  1.  
  2. $a = array(1,2,3,4,5);
  3. $s = sizeof($a);//you may use count(), but sizeof if 5% faster :)
  4. for ($i = 0; $i < $s; $i++)
  5. {
  6. //do something clever here
  7. echo $a[$i].‘
  8. ‘;
  9. }
  10.  

But this requires counting number of elements before using a loop. Continue reading ‘Nice trick with FOR loop’ »
