some codecandies I just find sometimes...

codecandies_001.php

<?php 

// most complicated way to reformart a date... also deprecated function 

ereg("([0-9]{4}).([0-9]{2}).([0-9]{2})", $value['check_in'], $alter);
$bdate="$alter[3].$alter[2].$alter[1]";
echo $bdate;

codecandies_002.php

<?php  
ini_set('display_errors', '1'); error_reporting(E_ALL);
session_start();

// [...]
// some requires and includes that could already sent some errors...
// [...]

$userName = $_SESSION['user'];
if(isset($userName)){ // check user is logged in (lol) 
}else{
    header('location:index.php');
}

codecandies_003.php

<?php
// could be easier to get GMT Date with 2 hours added

echo gmdate('D, d M Y H:i:s', mktime(date("H")+2,date("i"),date("s"),date("m"),date("d"), date("Y"))) . " GMT";

// found in an codecanyon pure php application.

codecandies_004.php

<?php

function konv_date($date){
  $jahr = substr($date,0,4);
  $mon  = substr($date,5,2);
  $tag  = substr($date,8,2);
  $datneu = $tag.'.'.$mon.'.'.$jahr;
  return $datneu;
  // return date('d.m.Y', strtotime($date)); would do the same... and would be safer ... and faster...
}
