2. Email validation snippet in PHP
$email = $_POST['email'];
if(preg_match("~([a-zA-Z0-9!#$%&'*+-/=?^_`{|}~])@([a-zA-Z0-9-]).([a-zA-Z0-9]{2,4})~",$email)) {

3. Parsing XML in easy way using PHP.

<moleculedb>
<molecule name='Benzine'>
<symbol>ben</symbol>
<code>A</code>
</molecule>
<molecule name='Water'>
<symbol>h2o</symbol>

</molecule>
</moleculedb>";
$xml = simplexml_load_string($xml_string);
foreach ($xml->molecule as $record)
{
echo $record['name'], ' ';
echo $record->symbol, ' ';
echo $record->code, '<br />';
}
4. Generate An Authentication Code in PHP
<?php
# This particular code will generate a random string
# that is 25 charicters long 25 comes from the number
# that is in the for loop
$string = "abcdefghijklmnopqrstuvwxyz0123456789";
for($i=0;$i<25;$i++){
$pos = rand(0,36);
$str .= $string{$pos};
}
echo $str;
# If you have a database you can save the string in
# there, and send the user an email with the code in
# it they then can click a link or copy the code
# and you can then verify that that is the correct email
# or verify what ever you want to verify
?>
5. HTTP Redirection in PHP
<?php
header('Location: http://you_stuff/url.php'); // stick your url here
?>
Following is the PHP code to create the JSON data format of above example using array of PHP.
$json_data = array ('id'=>1,'name'=>"rolf",'country'=>'russia',"office"=>array("google","oracle"));
echo json_encode($json_data);
Following code will parse the JSON data into PHP arrays.
$json_string='{"id":1,"name":"rolf","country":"russia","office":["google","oracle"]} ';
$obj=json_decode($json_string);
echo $obj->name;
echo $obj->office[0];
7. Database Connection in PHP
<?php
if(basename(__FILE__) == basename($_SERVER['PHP_SELF'])) send_404();
$dbHost = "localhost";
$dbUser = "xxxx";
$dbPass = "xxxx";
$dbDatabase = "xxxx";
$db = mysql_connect("$dbHost", "$dbUser", "$dbPass") or die ("Error connecting to database.");
mysql_select_db("$dbDatabase", $db) or die ("Couldn't select the database.");
# This function will send an imitation 404 page if the user
# types in this files filename into the address bar.
# only files connecting with in the same directory as this
# file will be able to use it as well.
function send_404()
{
header('HTTP/1.x 404 Not Found');
print '<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">'."n".
'<html><head>'."n".
'<title>404 Not Found</title>'."n".
