HTML is static and boring


PHP brings web pages to life


Form help us capture the data


Forms are made of HTML

HTML acts on the Client and ....

PHP acts on the SERVER


Use PHP to Access the Form Data

$_POST['var_name'] ...... [1]
$_GET_['var_name'] ...... [2]

PHP scripts must live on a server!

Get your PHP scripts to the server

Copy the example scripts to the root directory of the
server, or .....
You can setup a new virtual host


The server turns PHP into HTML


Deconstructing Owen's PHP scripts

//open : examples/ch01/final/aliens/report.php


A few PHP rules to code by
● PHP code always enclosed by <?php and ?>
● Every PHP statement must end with semicolon (;)
● If there is any PHP code in a web page, it's a
good idea to name the file on the web with .php
not .html
● PHP variable must begin with a dollar sign ($)


Finding the perfect variable name
● The first character must be a dollar sign ($)
● A variable name must be at least one character in length
● The first character after the dollar sign can be a letter or an
underscore (_), and characters after that can be a letter, an
underscore, or a number
● Spaces and special character other than _ and $ are not
allowed in any part of variable name
● (+) Use lowercase for variable name
● (+) Separate words in a multi-word variable name with
under score


Variables are for storing script data
● $where = “at home”
● $_POST[“email”] = “twetme@someplace.com”

//see : slide 6, for more information about $_POST and $_GET variable


Sending Email with PHP

bool mail ( string $to , string $subject , string $message [, string
$additional_headers [, string $additional_parameters ]] )

//see : http://id2.php.net/manual/en/function.mail.php

Creating Apache Alias

Alias /headfirst/ "/path/to/examples"
<Directory "/path/to/examples">
Options Indexes MultiViews FollowSymLinks

</Directory>


Create Database
● mysql> create database headfirst ;
● mysql> grant all on headfirst.* to
'headfirst'@'localhost' identified by 'jagungbakar' ;
● mysql> flush privileges ;


Add New Connection on Power Architect
