Most websites that use PHP simple have the extension of the page removed. This leads to cleaner, shorter, and easier to read URLs. It is also better for your SEO or Search Engine Optimization.

Using a simple .htaccess file with a few lines we can automatically add the .php file extension to any URL without it. This means something like example.com/page will look like example.com/page.php to the computer, but still retain the cleaner look of example.com/page to the user. Note: You can still explicitly call any page even with this change.

Step #1

Step #2

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]

Step #3

To keep your users from getting lost you should add a 404 redirect as well. If a user enters a wrong URL the web server will try to display that wrong page with a .php extension. To fix this, a 404 redirect will redirect all non-existent URLs to a predetermined 404 page. Note you will have to have some sort of 404 page for this to work. Don’t forget to change http://example.org/404 to the URL of your own 404 page.
 

ErrorDocument 404 http://example.org/404

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]

Simple PHP IRC Logger is a simple PHP IRC Bot class designed to connect to an IRC server, and generate HTML log files. It is based on a modified version of  Simple PHP IRC Bot. This script is designed and intended to be built upon for your needs, so if you have any problems please ask in our forum. Please also follow some of the notes below for guidance. For future updates and scripts, don’t forget to subscribe.

Features and Functions

• !join #channel – Joins the specified IRC channel
• !part #channel – Leaves the specified IRC channel
• !say #channel Message – Says message in the specified IRC channel
• !restart – Quits and restarts the script. (Helpful while testing the script)
• !shutdown – Quits and stops the script.

Usage and output:

<random-user> !say #nystic_chat hello there
<wildphp-bot> hello there

• Enable/Disable Logging (PHP Script Variable)
• Enable/Disable Logging Warning Message (PHP Script Variable)

Note the script in the current version of the script, all joined channels will be added to the single log file for the day.

Installation

1. Download or copy paste the script from this page
2. (Optional) If downloaded rename the file to bot.php ( Sorry, the blog will only allow me to upload it as log-bot.txt)
3. Edit the $config array in the script to the server settings, should be self explanatory
4. Download and install XAMPP
5. Place bot.php in the htdocs folder of your XAMPP installation
6. Don’t forget to start the Apache server by pressing the start button in the XAMPP Control Panel
7. Go to http://localhost/log-bot.php, and the bot should connect and join the channel you specified in about 30 seconds
8. If you have warning enabled the bot should say “Chat Logging has been [Enabled]” when entering the default room
9. If you have logging enabled an HTML file should appear in the same directory, it will be updated when anyone says something in the room

Programming Projects

Project One: Write a HTML form and PHP script that takes someones order.

Show Answer ▼

<html>
<head>
<title>Final Code Challenge</title>
</head>
<body>
<form action="index.php" method="post">
What drink do you want?: <input type="text" name="drink" /><br/>

echo "To eat you would like ".$_POST["eat"]."<br/>";
echo "For dessert you would like ".$_POST["dessert"]."<br/>";
?>

Project Two: Use the GET method to break down the following statement “?one=you&two=have&three=done&four=it”. (Add it to the end of the URL of the page)

Conclusion

Well that concludes our brief introduction to PHP. There is so much more to learn, so stick around for more. Don’t forget to subscribe on the right of the page. If you have any requests for tutorials or scripts, please let us know in the feedback section of the forum.

<title>Flipping Forms Tutorial</title>
</head>
<body>
The following is a form: <br/>

<form action="index.php" method="get">
What is your favorite book?: <input type="text" name="book" /><br/>
What is your favorite movie?: <input type="text" name="movie" /><br/>
What is your favorite website?: <input type="text" name="website" /><br/>
<input type="submit" />
</form>
</body>
</html>

Now the difference between GET and POST is a matter of visibility. When we hit the submit the POST data “magically” goes to the next page. With GET the data is put on the end of URL. When you hit submit you should see something like this on the end of your URL ?book=Harry+Potter&movie=Star+Wars&website=WildPHP+of+Course! .To print out the variables like last time we just use $_GET instead of $_POST:

Printed Results:

<?php
//Print out our GET Data
echo “Favorite Book: “.$_GET["book"];
echo “Favorite Movie: “.$_GET["movie"];
echo “Favorite Movie: “.$_GET["website"];
?>

Sample Output:

Favorite Book: Harry Potter
Favorite Movie: Star Wars
Favorite Website: WildPHP of Course!

Now that the data is viewable in the URL it probably won’t be the best idea to send passwords or sensitive data via GET. GET however can be very useful because we can pass information to PHP without having to fill out a form. If you look above at the URL you are at right now you can see GET in use. Using the info in the URL, PHP knows what post to pull up.

If you want to create a GET variable in a URL just follow this simple format: ?varname=value&varname2=value2. Notice that it always starts with a question mark, and additional values can be added with an ampersand(&).

<html>
<head>
<title>Flipping Forms Tutorial</title>
</head>
<body>
The following is a form: <br/>

<form action="index.php" method="post">
What is your favorite book?: <input type="text" name="book" /><br/>
What is your favorite movie?: <input type="text" name="movie" /><br/>
What is your favorite website?: <input type="text" name="website" /><br/>
<input type="submit" />
</form>
</body>
</html>

If you didn’t notice the slight change I made was method=”post”. This specifies the type of data our form should send. Now on to the PHP. Putting some text in box and hitting submit is not going to do us much good, so let’s capture it and print it out. Put this PHP code under the </form> tag.

Printed Results:<br/>

<?php
//Print out our Post Data
echo "Favorite Book: ".$_POST["book"]."<br/>";
echo "Favorite Movie: ".$_POST["movie"]."<br/>";
echo "Favorite Website: ".$_POST["website"]."<br/>";
?>

Sample Output:

Favorite Book: Harry Potter
Favorite Movie: Star Wars
Favorite Website: WildPHP of Course!

As you can see from the code we get the post data and print it out once you hit submit. The simple $_POST["var name"] statement allows us to do that.

<html>
<head>
<title>Flipping Forms Tutorial</title>
</head>
<body>
The following is a form:
</body>
</html>

In previous tutorials we have manually entered our integers and strings. For this we needed access to our PHP file to change the values. This would not be particularly helpful to a typical user on your website. HTML forms allow us to submit values to PHP which we can process. Let’s make a simple form

<html>
<head>
<title>Flipping Forms Tutorial</title>
</head>
<body>
The following is a form:

<form action="index.php">
What is your favorite book?: <input type="text" name="book" />
What is your favorite movie?: <input type="text" name="movie" />
What is your favorite website?: <input type="text" name="website" />
<input type="submit" />
</form>

</body>
</html>

Let’s go through the HTML one part at a time. If you are already well versed in HTML you should be able to skip this tutorial, and move on to the next one on POST.

Action=”index.php” – This line is the document that you are directed to after you hit the submit button. I am assuming you are still using index.php to run your PHP code .If you are not, you will have to modify it to the one you are using. You can direct it to a completely different one to run your PHP code there as well (more in the next tutorial).

<input type=”text” name=”book” /> – In this line we have the textbox type which is text for textbox. We also have a name which is very important. Follow the same rules as the PHP variable names to keep everything simple. We will use this name to access it in PHP so keep it simple and short.

<input type=”submit” /> – Our submit button. You can also add value=”Your Text”, to change the text from “Submit Query”.

Now that you have a little more knowledge with PHP forms, we can move on to more fun things!

Q: What is an array index?

Show Answer ▼

Programming Projects

Project One: Write a program that prints out “I Love WildPHP.com!” 10 times. Use While and For loops.

Show Answer ▼

<?php
//For Loop
for($i=1; $i<=5; $i++)
{
echo "I Love WildPHP.com! ";
}

//While Loop
$i=1;
while($i<=5)
{
echo "I Love WildPHP.com! ";
$i++;
}
?>

Project Two: Write a loop that will add all the numbers in the following integer array: 22, 56, 7, 32, and 11.

Show Answer ▼

<?php
//Declare Array
$numbers = array(22, 56, 7, 32, 11);

//Sum Variable
$sum = 0;

//For Loop
for($i=0; $i<5; $i++)
{
$sum += $numbers[$i];
}

echo "The sum is ".$sum;
?>

Arrays can store all types of values from string to integers to many different types we have yet to go over. Lets try out a simple array before we move on to our example:

<?php
//One way to declare an array
$apartment = array("Ground Floor","Floor 1","Floor 2","Floor 3");

//Other way to declare an array
$apartment[0]="Ground Floor";
$apartment[1]="Floor 1";
$apartment[2]="Floor 2";
$apartment[3]="Floor 3";

//Print out a floor name
echo $apartment[2];
?>

Output:

Floor 2

Think of an array as a stack of variables. Instead of creating a bunch of variables, we can simply create an array. The individual values in an array, by it’s index. If your confused you can think of an array as a building with individual values on each floor. If we specify we want to go to index or “floor” 0, remember we always start from zero in PHP, we might find a stored value like “chocolate.” If we where to go to 6th index or “floor” we could find a value like vanilla.

<?php
//Declare our array
$flavors = array("Chocolate ", "Strawberry ", "Butter pecan ", "Neapolitan ",
"Vanilla fudge ripple ", "French vanilla ", "Vanilla ", "Cookies and cream ");

//Edit a flavor
$flavors[0] = "Chocolate chip ";

//Print our flavors
echo "Our Flavors: ";
for($i=0; $i<=7; $i++)
{
echo $flavors[$i];
}
?>
