Basic PHP Syntax

A PHP script can be placed anywhere in the document.

A PHP script starts with <?php and ends with ?>:

<?php
// PHP code goes here?>

The default file extension for PHP files is ".php".

PHP Variables

A variable can have a short name (like x and y) or a more descriptive name (age, carname, total_volume).

Rules for PHP variables:

• A variable starts with the $ sign, followed by the name of the variable
• A variable name must start with a letter or the underscore character
• A variable name cannot start with a number
• A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )
• Variable names are case-sensitive ($age and $AGE are two different variables)

Output Variables

The PHP echo statement is often used to output data to the screen.

PHP Arithmetic Operators

The PHP arithmetic operators are used with numeric values to perform common arithmetical operations, such as addition, subtraction, multiplication etc.

Operator	Name	Example	Result
+	Addition	$x + $y	Sum of $x and $y
-	Subtraction	$x - $y	Difference of $x and $y
*	Multiplication	$x * $y	Product of $x and $y
/	Division	$x / $y	Quotient of $x and $y
%	Modulus	$x % $y	Remainder of $x divided by $y
**	Exponentiation	$x ** $y	Result of raising $x to the $y'th power

 ^.^ i used visual studio code to do this assigment but if you didnt have this program, maybe you could use online program like http://www.writephponline.com/

Let's see :

1. 
   Ada seorang nasabah bank yang menabung di bank X dengan saldo awal Rp. 1.000.000,-. Bank X menerapkan kebijakan bunga 3% perbulan dari saldo awal tabungan. Hitunglah jumlah saldo akhir nasabah tersebut setelah 11 bulan. Lengkapi programnya dan tampilkan outputnya
   
   
    <?php
   $saldoAwal = 1000000;
   $bunga = 0.03;
   $bulan = 11;
   $saldoAkhir = …;
   echo “Saldo akhir setelah “.$bulan.” bulan adalah : Rp. “.$saldoAkhir. “,-“;
   ?>
