Array(key=>value)

The array in the syntax refers to the name of the array being created, the key is the index which is set automatically to a numeric character or string if none is specified. Value is the assigned value or content of the said array which can be seen easily in the following array creation example:

$b=array('z'=>‘Comedy”,’y'=>”Horror”,’x;’=>”Action”);
print_r($b);
?>

This piece of code would produce an output of :

Array ([0] => Comedy [1] => Horror [2] => Action)

V. Operators in PHP

*Arithmetic Operators*

+ addition
- subtraction
* multiplication
/ division
% modulus (division remainder)
++ increment
– decrement

*Comparison Operators*
== equal to
!= not equal
> greater than
= greater than or equal
<= less than or equal

*Logical Operators*
&& and
|| or
! not

I know its self explanatory…

VI. IF….Else Statements

If (condition)
//*Things to be executed if the answer to the condition is true*//
else
//*Things to be executed if the answer to the condition is false*//

If…else statement is use if the user wants to execute a set of code when the condition is true and another if the condition is not true.

VII. Switch Statement

switch (expression)
{
case 1:
//*code to be executed*//
break;
case 2:
//*code to be executed*//
break;
default:
//*code to be executed*//
break;
}

Switch statement is use if you want to select one of many blocks of code to be executed. this statement is used to avoid long blocks of if…elseif..else.

VIII. Looping Statement

while(condition)
code to be executed;

While statement is used to execute a block of code if and as long as a condition is true

do
{
code to be executed;
}while (condition)

Do—while statement is used to execute a block of code at least once and it will repeat the loop as long as the condition is true.

for each (array as value)
{
code to be executed;
}

For each statement is used to loop through arrays.

I think this is already enough and it has added new knowledge to those who are new in PHP… good luck and happy coding…

$variablename=value;

Variables are used for storing values such as text string or arrays. And all variables in PHP starts with a ($) dollar sign. There are various rules to be follow before naming a variable. 1) A variable name must start with a letter or an underscore. 2) A variable name can only contain alpha-numeric characters and underscores. Special characters are not allowed. 3) A variable name should not contain spaces.

IV.PHP Strings

$wrd=”Hello World”;
print $wrd;

Strings variables are used for values that contain character strings. The only operator that can be used on string is concatenation denoted by the sign (.) period.

$wrd1=”Hello World”;
$wrd2=”Good day”;
print $wrd1.”".$wrd2

You can count the nos. of string with the function strlen().

Print strlen(”HelloWorld and GoodDay”);

On the other hand, Microsoft’s Internet Information Server (IIS) is a group of internet servers which has additional fetures for Microsoft operating system such as Windows NT and windows 2000 operating system servers. IIS can’t use Java, Perl and PHP on a .Net platform because Microsoft doesn’t support those technologies but Web developers can use Microsoft’s Active Server Page (ASP)technology otherwise. IIS has server administrators which include console from which all services and users can be administered. According to www.microsoft.com “I IS 6.0 which is redesigned with a new fault-tolerant process architecture that greatly boosts the reliability of Web sites and applications. IIS 6.0 isolates Web sites and applications into self-contained units called application pools, which separate applications from the other applications that are hosted on the same server.” Now i give you free hand to choose on what server you want to use? IIS or APACHE?

PHP is originally known as Personal Homepage but now it’s already known as Hypertext Preprocessor. This general-purpose scripting language was created by Rasmus Lerdorf in 1995. And its main use is to produce Dynamic Web Pages.

PHP is one of the widely-used scripting languages over the web servers because it’s free of charge. PHP can also be used for command-line scripting and client-side GUI application. And in terms security, PHP is the popular target of hacker especially those application that is poorly built.

PHP focuses on server-side scripting. And it’s like other server-side scripting languages that provide dynamic content from a web server to a client such as Microsoft ASP.NET, Sun Microsystem JavaServer Pages and mod_perl.

According to wikipedia.com “PHP is the fourth to the most popular computer programming language, ranking behind JAVA, C, and Visual Basic. PHP was also recorded as the most popular Apache module. And as of April 2007, 20 million Internet domains were hosted on servers with PHP installed.”

This web development package allows web developer to create web applications using APACHE(server), PHP(coding), and the MySQL(database). Plus it has PHPMyAdmin and SQLiteManager that make web developer managed their database easily.

This is the only program allows the user to reproduce their production server. That’s why there is the possibility that you can add as many apache, mysql or php releases you want.
