Learn PHP on 15 Minutes

Step 1:

To be able to execute PHP scripts, you need at least a working PHP installation+ web server. Linux, Apache, MySQL and PHP are the best combinations. PHP also can run under Microsoft Windows, too.

PHP installation and configuration can be made easy with tools such as Apache2Triad or XAMPP which automate web server and PHP installation.

PHP script is stored in text format file so you need text editor. Notepad and Notepad++ are enough for your PHP development needs. However, you may opt to invest in more advanced tools such Dreamweaver or Eclipse.
Step 2:

PHP script is anything between pair. You can also use . The first is most widely used.




print '

Hello this is my first script

';
?>



Output of the following code will be same as the previous code:

print '

Hello this is my first script

';
?>

Step 3:

The power of PHP lies on the capability to change how HTML code will output. The following code will output different HTML codes when you change the name.




$aname=$_GET['name'];
print '

Hello '.$name.' this is my first script

'; ?>




Save this script as welcome.php in the document root directory (for Apache web server, this is usually htdocs directory). Open your web browser and type http://localhost/welcome.php?name=Zamrony

Step 4:

$_GET is a predefined variable which stores lists of parameters passed to the script. It is an array. If you change http://localhost/welcome.php?name=zamrony&country=Indonesia, $_GET will contain more items.




$aname=$_GET['name'];
$acountry=$_GET['country'];
print '

Hello '.$name.' from '.$acountry.' .
this is my first PHP script

';
?>



It will print Hello Zamrony from Indonesia. This is my first PHP script.

Step 5:

$aname, $acountry and $_GET are all variables in PHP. Any variables in PHP should be prefixed with dollar sign. Variable names must only contain alphanumeric and underscore characters where the first character in variable names should be alphabet characters or underscores.

This is invalid variable name:

$123
$1aname
$*jskk

This is valid variable name:

$k123
$j
$_
$_test
$k123k
$KK


PHP is case sensitive. Variable $kk is not $KK.

How to Create a Basic Login Script in PHP

Interested in creating your own forum page, blog, or even a shopping cart? A login area is the first step. Here is how to create a script for it in PHP.

Steps:

1. Create the login database and table. For the purposes of the code examples below, we will assume the database name to be "test" and the table name to be "members". The database and table can be created through the control panel of your webhost. The "members" table will store the username and the passwords of all the people would be allowed access via this login script. The table should have a unique id field as the primary key, a username field, and a password field.


2. Create the login interface. This is an html page containing a form, two text boxes for the user name and password, and a submit button. As long as you have these elements, you may design the layout however you wish.

Example:

Member Login
Username:
Password:

3. Create the php script that will check the login input against the database. This script will connect to the database, send a query and retrieve the result, check to see if the username and password is correct and send you to the next page depending on the result of the comparison.

Example (connecting to the database):

$host="localhost"; // Host name
$username=""; // username
$password=""; // password
$db_name="test"; // Database name
$tbl_name="members"; // Table name

// Replace database connect functions depending on database you are using.
mysql_connect("$host", "$username", "$password");
mysql_select_db("$db_name");


Example (submitting query and retrieving results):

// username and password sent from form
//NEVER Remove the mysql_real_escape_string. Else there could be an Sql-Injection!
$myusername=mysql_real_escape_string($_POST['myusername']);
$mypassword=mysql_real_escape_string($_POST['mypassword']);

$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);


Example (checking results):

// Replace counting function based on database you are using.
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row


Example (direct user based on result):

if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");
header("location:login_success.php");
} else {
echo "Wrong Username or Password";
}

4. Create the page that will display after login success. This script will start your session and display an html message of your choosing.

Example:

// Check if session is not registered , redirect back to main page.
session_start();

if(!session_is_registered(myusername)){
header("location:main_login.php");
}
?>



Login Successful



5. Create logout script. This step is optional as sessions can time out. If you wish to create one, you will need a button or link to initiate the script and a message to confirm the success of logging out.

Example:

session_start();
session_destroy();
?>


Tips

* Replace the database functions in your script with the appropriate functions for the database you are using (e.g. SQLITE, Microsoft SQL, etc.)

* Depending on your requirements, add security checks to your script.

* Try using CSS and various HTML elements to create an interesting look for your login and message pages.
