PHP: phpMyAdmin3 - deactivate slider effects

For all of you who liked phpMyAdmin2 where all relevant information was visible at any time, sould be annoyed be the new slider effects in phpMyAdmin3.
I did a short search for the config value to change this and found this solution.

Add this to your config.inc.php:

// Change slider behaviour
$cfg['InitialSlidersState'] = 'open';

And your sliders will start in visible state.

phpMyAdmin download:

PHP: floor() and ceil() are slow!

A workmate mentioned, that floor($i) could be replaced with (int)$i.
I found this very interresting and did some researched about that.

floor($i); will return a float that will have the lower value of $i.
A cast will just convert $i to an integer which will cut of all decimals.
So by symptoms, these two methods are equivalent. Even if floor returns a float, PHP does dynamic casting of its variables.

PHP: Do NOT rebuild preg_* functions!

In a PHP Project i am currently helping out, i found this function:

/**
 * Replaces every char in $str that does is not in $valid array
 *
 * @param array $valid
 * @param string $str
 * @return string
 */
function cleanString($valid, $str) {
  $ret = '';
  $len = strlen($str);
  for($i = 0; $i < $len; ++$i) {
    if(in_array($str[$i], $valid, true)) {
      $ret .= $str[$i];
    }
  }
  return $ret;
}

It is a simple function for replacing chars. It works quite well, but was mainly only used for checking [^a-z0-9]. So i tested the speed of this code.

In a current project of mine i needed the use of a universal caching system.
After testing a little bit with APC i found memcache that will do the job perfectly.
So i wrote a few tiny functions for easy memcache handling.

Rewrite: PHP String Flipper Class

I found this class on Twitter. Nice idea flipping chars by replacing them with their unicode upside down alternative.
But what bugged me was the code, it looked awful. So id did a rewrite to clean it up a little bit.

Easy to use and secure PHP hashing Class

Why

I created this class because there are too many people still saving simple md5 instead of more secure hashes.
The class should be fully PHP4 and PHP5 compatible and very easy to use. But also extended usage on its complex methods is possible.

Example

The usage of the class should be straight forward.
If you just want to use it, use the methods hash() and check().
EXAMPLE:

$secure_hash = new secure_hash;
$hash = $secure_hash->hash('pass');
if($secure_hash->check($hash, 'pass'))
  echo "Password fits to hash.";
else
  echo "Password does NOT fit to hash.";

That is all you need to know for just using it, but i have to tell, you will miss something important if you stop reading here.
