PHP - RSS Generator

PHP - RSS Generator

You'll need a MySQL database with a a table called `rss_feed`. In that table there are 3 colums:item title (which is the name a person will see for an item), the item link (which is the location of the page with the item on it), and description (which tells what the feed is about). Put the file in a folder called feed and you're feed will be available at yoursite.com/feed

Remember to change the feed title, link and image for your specific feed.

<?php

// Connect to database... (you'll need to create this yourself)

require_once $_SERVER['DOCUMENT_ROOT'] . '/includes/connection.php';

// Run query...

$getFeed = mysql_query("SELECT *

FROM `rss_feed`

ORDER BY `time` DESC

")or die(mysql_error());

// Output XML (RSS)

echo '<?xml version="1.0" encoding="ISO-8859-1" ?>

<title>Your RSS Title</title>

<description>Description of your Feed</description>

<language>English</language>

<image>

<title>website Logo</title>

<width>width</width>

<height>height</height>

</image>';

while($rssFeed = mysql_fetch_array($getFeed)) {

echo '<item>',

'<title>', $rssFeed['item_title']</title>',

'<link>', $rssFeed['link'], '</link>',

'<description><![CDATA[ ,$rssFeed['description'],']]></description>

</item>';

}

echo '</channel>

</rss>';

PHP - Send Email

PHP - Send Email

HTML Form with Inputs

<form action="" method="post">
<label for="name">Name:</label>
<input type="text" name="name" id="name" />

<label for="Email">Email:</label>
<input type="text" name="email" id="email" />

<label for="Message">Message:</label><br />
<textarea name="message" rows="20" cols="20" id="message"></textarea>

<input type="submit" name="submit" value="Submit" />
</form>

Process with PHP (sendemail.php)

<?php
// from the form
$name = trim(strip_tags($_POST['name']));
$email = trim(strip_tags($_POST['email']));
$message = htmlentities($_POST['message']);

// set here
$subject = "Contact form submitted!";
$to = 'your@email.com';

$body = <<<HTML
$message
HTML;

$headers = "From: $email\r\n";
$headers .= "Content-type: text/html\r\n";

// send the email
mail($to, $subject, $body, $headers);

// redirect afterwords, if needed
header('Location: thanks.html');
?>

Login Function

These functions will log in a user based on a username and password being matched in a MySQL database.

login($username, $password);

// function to escape data and strip tags
function safestrip($string){
$string = strip_tags($string);
$string = mysql_real_escape_string($string);
return $string;
}

//function to show any messages
function messages() {
$message = '';
if($_SESSION['success'] != '') {
$message = '<span class="success" id="message">'.$_SESSION['success'].'</span>';
$_SESSION['success'] = '';
}
if($_SESSION['error'] != '') {
$message = '<span class="error" id="message">'.$_SESSION['error'].'</span>';
$_SESSION['error'] = '';
}
return $message;
}

// log user in function
function login($username, $password){

//call safestrip function
$user = safestrip($username);
$pass = safestrip($password);

//convert password to md5
$pass = md5($pass);

// check if the user id and password combination exist in database
$sql = mysql_query("SELECT * FROM table WHERE username = '$user' AND password = '$pass'")or die(mysql_error());

//if match is equal to 1 there is a match
if (mysql_num_rows($sql) == 1) {

//set session
$_SESSION['authorized'] = true;

// reload the page
$_SESSION['success'] = 'Login Successful';
header('Location: ./index.php');
exit;

} else {
// login failed save error to a session
$_SESSION['error'] = 'Sorry, wrong username or password';
}
}

All pages involved would have the messages function somewhere so proper use feedback is given:

messages();

{
//Perform a basic syntax-Check
//If this check fails, there's no need to continue
if(!filter_var($email, FILTER_VALIDATE_EMAIL))
{
return false;
}

//extract host
list($user, $host) = explode("@", $email);
//check, if host is accessible
if (!checkdnsrr($host, "MX") && !checkdnsrr($host, "A"))
{
return false;
}

return true;
