Our first Piece of CODE The Script Tags All PHP code is contained in one of several script tags: <? // Some code ?> <?php // Some code here ?>

The Script Tags

All PHP code is contained in one of several script tags:

<? // Some code ?>

<?php // Some code here ?>

The Hello World Example <?php echo “Hello world”; ?> Our first Piece of CODE

The Hello World Example

<?php

echo “Hello world”;

?>

Variables All variables starts with $ i.e $var1 =“ Motiur Sir” and $var2 =“ The Boss !!” How to print “ Motiur Sir The Boss !!”

All variables starts with $

i.e

$var1 =“ Motiur Sir”

and

$var2 =“ The Boss !!”

How to print “ Motiur Sir The Boss !!”

Exapmle The Hello World Example <?php echo $var1.$var2 ; ?> Output “ Motiur Sir The Boss !!”

The Hello World Example

<?php

echo $var1.$var2 ;

?>

Output

“ Motiur Sir The Boss !!”

Arrays Very important Topic Declaring an array $arrayExample= array(); $arrayExample= array( ‘ Nazrul Islam’, ‘ Is’, ‘ COOL’ );

Very important Topic

Declaring an array

$arrayExample= array();

$arrayExample= array(

‘ Nazrul Islam’,

‘ Is’,

‘ COOL’

);

Built in Function : print_r() I use this function for Debugging print_r( $arrayExample ); Output: Array ( [0] => Nazrul Islam [1] => Is [2] => COOl!! )

I use this function for Debugging

print_r( $arrayExample );

Output:

Array ( [0] => Nazrul Islam

[1] => Is

[2] => COOl!! )

Functions Two Types of Functions Built in Functions User defined functions

Two Types of Functions

Built in Functions

User defined functions

Built in Function Example bool empty(); empty -- Determine whether a variable is empty bool isset(); isset -- Determine whether a variable is set . string date(); date -- Format a local time/date

bool empty();

empty -- Determine whether a variable is empty

bool isset();

isset -- Determine whether a variable is set .

string date();

date -- Format a local time/date

User Defined Functions Starts with keyword function Our first function function you_fail ($name ) { echo “ Sorry $name you have failed ” }

Starts with keyword function

Our first function

function you_fail ($name )

{

echo “ Sorry $name you have failed ”

First Normal Form First Normal Form Each column in a row must be atomic. Each row in a table must contain the same number of columns. All rows in a table must be different.

First Normal Form

Each column in a row must be atomic.

Each row in a table must contain the same number of columns.

All rows in a table must be different.

Second Normal form The table must be in first normal form. All nonprimary key columns in the table must be dependent on the entire primary key. Why Normalization ?

The table must be in first normal form.

All nonprimary key columns in the table must be dependent on the entire primary key.

Why Normalization ?

Why Normalization ? Key point : Reducing data redundancies.

Data retrieval by PHP Step1: setting up - user ,host, password Step2: connceting to mySQL Step3: selecting database selecting studentInfo database

Step1: setting up - user ,host, password

Step2: connceting to mySQL

Step3: selecting database

selecting studentInfo database

Step1 define ( host, &quot;localhost&quot;); define ( user, &quot;root&quot;); define ( pass, &quot;&quot;); define ( DB, “studentInfo&quot;);

define ( host, &quot;localhost&quot;);

define ( user, &quot;root&quot;);

define ( pass, &quot;&quot;);

define ( DB, “studentInfo&quot;);

Step 2: $con = mysql_connect ( host ,user ,pass ); if( ! $con) { echo &quot;Error in connection &quot;. mysql_error(); }

$con = mysql_connect ( host ,user ,pass );

if( ! $con)

{

echo &quot;Error in connection &quot;. mysql_error();

}

Step 3 $DB_sel= mysql_select_db ( DB , $con); if( ! $DB_sel ) { echo “Database Not Found &quot;. mysql_error(); }

$DB_sel= mysql_select_db ( DB , $con);

if( ! $DB_sel )

{

echo “Database Not Found &quot;. mysql_error();

}
