HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://yourtargetURL.org");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

This will work fine, however your connection will not be anonymous. Using Tor, you can effectively create an anonymous connection. First, make sure to install Tor and run it. The typical Tor Windows install will install Privoxy along with Vidalia. To make your C# web request run through Tor, you need to override the default proxy property to contact Prioxy.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://yourtargetURL.org");
request.Proxy = new WebProxy("127.0.0.1:8118"); // default privoxy port for tor
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

127.0.0.1:8118 is the default address for Privoxy. Your HttpWebRequest will now be routed through Tor. Make sure that you do not have any firewalls blocking this default port.

First, you’ll need a MySQL result set. To do that you’ll need to select something from your database and loop through it like so:

$result = mysql_query("SELECT * FROM my_table");

while($row = mysql_fetch_assoc($result)) {

// inside the loop

}

The problem is, if you want to loop through the same result set again, you will get an error because the internal pointer is currently at the end of the result. You will need to put the pointer back at the beginning of the result set so that you can loop through it again.

You can do it with a helpful php function named mysql_data_seek.

mysql_data_seek($result, 0); // set the pointer of the result set back to the beginning.

while($row2 = mysql_fetch_assoc($result)) {

// inside the loop

}

This demonstrates how, as a PHP website developer, you can reset the pointer of a MySQL result set, which will allow you to iterate through the result set for a second time.

The ternary operator is a shorthand if/else statement. It allows developers to form conditions quickly and in a very readable fashion.

Here is the ternary syntax

(condition) ? true-stuff-here : false-stuff-here;

Here is an example of the ternary operator

$age = 20;

$response = ($age > 29) ? 'He's in his thirties' : 'He's not';

echo $response; // He's not

I hope you can see the usefulness in the ability for the ternary operator to easily perform conditional comparisons. Please however, refrain from using ‘nested ternary comparisons’ as the are very difficult to so read. It is so frowned upon by web developers that I’m not even going to post an example.

Sorting a PHP Array by Date

The first step is ensuring that the dates are placed into the array in proper format. When you add the date to the array, the best and most compatible way to do do is to run the PHP date function on the date value. This function works no matter what format the date is in, including a MySQL datetime column or a PHP timestamp.

So to enter dates into your array you can do something like:

$dateArray[] = date('Y-m-d');

//If you are iterating through something like a database with date's you could do something like:

$dateArray[] = date('Y-m-d', $row['date']);

One you have your date array set

All you need to do is run a  sorting function on the array.

Most recent date first

rsort($dateArray);

Oldest date first

sort($dateArray);

I hope this quick tutorial will help you in your website development and design endeavors!

The Apache Rewrite Code

RewriteEngine on

RewriteCond %{REQUEST_URI} !/theTempPage.php$

RewriteRule $ /theTempPage.php [R=307,L]

First we turn on the Rewrite engine (depending on your configuration .htaccess file it may already be on, however it won’t hurt Apache to include this if it is).

We then tell Apache to find pretty much everything after the domain name in a URL that is not equal to the maintenance page (in this case it is theTempPage.php).

If the URL is not equal to the condition, the user is forwarded to the maintenance page.

The function to check if value is within a two number range

function numberBetween($numToCheck, $high, $low) {
if($numToCheck <= $low) return false;
if($numToCheck >= $high) return false;
return true;
}

How to call the function

if (numberBetween(35, 100, 20)) {

echo 'The value is in the range!';

} else {

echo 'The value is outside the range!';

}

In this example, the value returned would be true because 35 is between 100 and 20.

I hope this data validation function will help you in your website development endeavors. It should simplify your development of a function that checks to see if a number (integer) falls between two values (range of numbers).

The URL Data Validation Function

function validateURL($URL) {
return (bool)preg_match("/^(http|https|ftp):\/\/([A-Z0-9][A-Z0-9_-]*(?:\.[A-Z0-9][A-Z0-9_-]*)+):?(\d+)?\/?/i", $URL);
}

How To Call The Function

if (validateURL('http://www.krio.me') {

// If URL is valid, do something here

}

Use this in all of your PHP scripts to ensure that input provided by users for URL’s is of a valid data type. Need a website developer to help you out? Contact me if you need some help. I’m a web developer and designer local to Miami, Florida.

This website scraper was developed by Kevin Rio, a Miami Website Developer,  for the purpose of collecting information and content from affiliate sites, such as E-Commerce applications that do not provide an API or an externally available database. It is also useful for SEO professionals to evaluate competitor websites.

This is a completely free website scraper that can be used in any commercial or private applications.

What This Website Scraper Does

This web scraper collects a website address as input from the user and retrieves all of the HTML code from that site. It then filters all of the HTML and JavaScript code using regular expressions and leaves only the website’s text for the user to explore. It provides the text in an easy to copy text area and a variable that is easy to manipulate and extend in your own scripts.

The download provides all of the files including the Visual Studio solution file.

Our XML File

Here is our XML file.

We are going to insert a new <Link> child element that holds sibling elements <title> and <url>.

<?xml version="1.0" encoding="ISO-8859-1"?>
<MyLinksCentral>
    <Links>
        <Link>
            <title>Krio Media</title>
            <url>http://www.krio.me</url>
        </Link>
        <Link>
            <title>SEO Miami</title>
            <url>http://www.mercadeoporinternet.com/</url>
        </Link>
    </Links>
</MyLinksCentral>

How To Add The XML Elements

And here is how we add the new elemnts to the document

  $xdoc = new DomDocument;
  $xdoc->Load('MyLinksCentral.xml');

        $links = $xdoc->getElementsByTagName('Links')->item(0);
        $newLinkElement = $xdoc ->createElement('Link');
        $newTitleElement = $xdoc ->createElement('title');
        $newURLElement = $xdoc ->createElement('url');

        $urlNode = $xdoc ->createTextNode ('Google');
        $titleNode = $xdoc ->createTextNode ('http://www.google.com');

        $newTitleElement -> appendChild($titleNode);
        $newURLElement -> appendChild($urlNode);

        $newLinkElement -> appendChild($newTitleElement);
        $newLinkElement -> appendChild($newURLElement);

        $links -> appendChild($newLinkElement);

$xdoc->save('MyLinksCentral.xml');

Step-By-Step Analysis Of The XML

Load – We load the XML file.

getElementsByTagName – We get the Links element, which holds all of our links.

createElement – We create the elements that we will be inserting into our XML file and save them into a variable.

createTextNode – We place the values of the elements into variables. In this case it is the URL and Title we want. We we will inserting Google as the Title and http://google.com as the URL.

appendChild – We put the text we just created into the actual elements <title> and <url>.

appendChild – The next set of appendChild’s are to place the complete <title> and <url> tags inside of our <Link> element.

The final appendChild is to insert the final <Link> tag into the <Links> element of the XML file to be saved.
