1.
2. What is PHP?
PHP is an HTML-embedded scripting language. The
goal of the language is to allow web developers to
write dynamically generated pages quickly.
3. PHP will allow you to:
Reduce the time to create large websites it’s an Open
Source Software.
Create a customized user experience for visitors
based on information that you have gathered from
them
4. What You Should Know
Before starting this tutorial it is important that you have
a basic understanding and experience in the
following:
HTML - Know the syntax and especially HTML forms.
Basic programming knowledge - This isn't required,
but if you have any traditional programming
experience it will make learning PHP a great deal
easier.
5. PHP Syntax
Syntax: The rules that must be followed to write
properly structured code
You can put your PHP code inside the body of HTML
The PHP code is enclosed with
<?php
//your code here.
?>
7. Example 2: HTML & PHP
<html>
<head>
<title>My First PHP Page</title>
</head>
<body>
<?php
echo "Hello World!";
?>
</body>
</html>
8. PHP - Variables
A variable is a means of storing a value, such as text string "Hello
World!" or the integer value 4. A variable can then be reused
throughout your code, instead of having to type out the actual value,
over and over again.
In PHP you define a variable with the following form:
Example:
$variable_name = Value;
Description:
If you forget that dollar sign at the beginning and the semi-colon at the
end, it will not work. This is a common mistake for new PHP
programmers!
9. Outputting a String.
PHP
<?php
echo "Hello!";
echo "<h5>I love using PHP!</h5>";
?>
Output
Hello!
I love using PHP!
10. Using Comment in PHP
Comments in PHP are similar to comments that are used
in HTML. A comment is started with a special character
sequence and all text that appears between the start of the
comment and the end will be ignored by the browser.
Single Line Comment
// this a single line statement
Multiple Line Comment
/* this is a multiple
line comment.
*/
11. Creating HTML form
<html><body>
<h4>ABC Art Supply Order Form</h4>
<form>
<select>
<option>Paint</option>
<option>Brushes</option>
<option>Erasers</option>
</select>
Quantity: <input type="text" />
<input type="submit" />
</form>
</body></html>
Output
12. PHP Form Processor
<html>
<body>
<?php
$quantity = $_POST['quantity'];
$item = $_POST['item'];
echo "You ordered ". $quantity . " " . $item . ".<br />";
echo "Thank you for ordering from ABC Art Supplies!";
?>
</body>
</html>
