PHP Program Using Operators

PHP program using operators - In general programming language, the operator is used to manipulate or perform the calculation process on a variable value. Variables whose value is modified by the operator are called operands.
To understand more about the operator in PHP the following explanation.

Operator Type	Operator	Example	Information
Arithmetic	+	$a + $b	Addition
	-	$a - $b	Subtraction
	*	$a * $b	Multiplication
	/	$a / $b	Division
	%	$a % $b	Modulus
Assignment	=	$a = 4;	$ A is filled with 4
Bitwise	&	$a & $b	Bitwise AND
	|	$a | $b	Bitwise OR
	^	$a ^ $b	Bitwise XOR
	~	~$b	Bitwise NOT
	<<	$a << $b	Shift Left
	>>	$a >> $b	Shift Right
Comparison	==	$a == $b	Equal
	===	$a === $b	Identical
	!=	$a === $b	Not equal
	<>	$a <> $b	Not equal
	!==	$a !== $b	Not identical
	<	$a < $b	Greater than
	>	$a > $b	Less than
	<=	$a <= $b	Less than or equal to
	>=	$a >= $b	Greater than or equal to
Logical	and	$a and $b	TRUE if $a dan $b TRUE
	&&	$a && $b	TRUE if $a dan $b TRUE
	or	$a or $b	TRUE if $a atau $b TRUE
	||	$a || $b	TRUE if $a and/or $b TRUE
	xor	$a xor $b	TRUE if $a or $b TRUE, But not both
	!	!$a	TRUE if $a FALSE
String	.	$a . $b	Concatenation string $a dan $b

To better understand about the operator in php, here I give examples of the use of the program using the php operator.
PHP program using operators
File Name: operator.php
Description: Program some arithmetic Operators in PHP.
Open notepad then input the following php code into notepad.
<?php
$salary = 1000000;
$tax = 0.1;
$taxyear = $salary - ($salary*$tax);
echo "Salary before tax = $. $salary <br>";
echo "The salary brought home = $. $taxyear";
?>

After that save with operator.php name (In the htdocs folder).
To see the results please open the browser and type in the address bar http://localhost/operator.php then the results will look like below.

File Name: operator2.php
Description: Logical programming and comparison operators in PHP.
Open notepad then type the following code into notepad.
<?php
$a = 5;
$b = 4;
echo "$a == $b : ". ($a == $b);
echo "<br>$a != $b : ". ($a != $b);
echo "<br>$a > $b : ". ($a > $b);
echo "<br>$a < $b : ". ($a < $b);
echo "<br>($a == $b) && ($a > $b) : ".(($a != $b) && ($a > $b));
echo "<br>($a == $b) || ($a > $b) : ".(($a != $b) || ($a > $b));
?>

Once the code is entered then save it with the name operator2.php (In the htdocs folder).
If you want to see the results please open the browser then type http://localhost/operator2.php on addres bar. Then the result will look like the following.
