Practical Slips: Advance PHP Slips Semester 4

Advance PHP

SLIP1. 

Write a PHP script to create a simple calculator that can accept two numbers and perform 

operations like add, subtract, multiplication. (Use the concept of Class).

<?php
class MyCalculator
{
private $fval, $sval;
public function __construct( $fval, $sval)
{
$this->fval = $fval;
$this->sval= $sval;
}
public function add()
{
return $this->fval + $this->sval;
}
public function subtract()
{
return $this->fval - $this->sval;
}
public function multiply()
{
return $this->fval * $this->sval;
}
public function divide()
{
return $this->fval / $this->sval;
}
}
$mycalc = new MyCalculator(18, 3);
echo "Addition: ",$mycalc-> add()."\n <br>";
echo"Multiplication: ",$mycalc->multiply()."\n <br>";
echo "Subtraction: ",$mycalc-> subtract()."\n<br>";
echo "Divide: ",$mycalc-> divide()."\n <br>";
?>

Slip 2. a) Write a PHP script to demonstrate the introspection for examining classes and objects. (Use function get_declared_classes(), get_class_methods() and get_class_vars()).

<?php
class Myclass
{
public $a;
public $b=1;
public $c='Mahesh';

function Myclass()
{ 
    //myclass function
}
function myfun1()
{
    //function
}
function myfun2(){
    //function
}
}
$class=get_declared_classes();
foreach($class as $cname)
{
    echo"$cname<br>";
}
echo"<br>Class Methods are : <br>";
$m=get_class_methods('Myclass');
foreach($m as $mname)
{
    echo"$mname<br>";
}
$cp=get_class_vars('Myclass');

{
    
    echo"$cpname: $v<br>";
}
?>

Advance PHP

Slip-3 a) Write a Calculator class that can accept two values, then add them, subtract them, multiply them together, or divide them on request.

<FORM method="get" action="#">
Enter first value: <input type="text" name="a">
<br><br>
Enter second value:<input type="text" name="b"><br><br>
<input type="submit" name="submit">
</FORM>
<hr>
</BODY>
</HTML>

<!-- calculate.php -->
<?php
class Calculate
{
public $a;
public $b;
function __construct($a,$b)
{
$this->a=$a;
$this->b=$b;
}
public function add()
{
$c=$this->a+$this->b;
echo"Addition = $c<br>";
}
public function subtract()
{
$c=$this->a-$this->b;
echo"Subtract = $c<br>";
}
public function multiply()
{
$c=$this->a*$this->b;
echo"Multiplication = $c<br>";
}
public function div()
{
$c=$this->a/$this->b;
echo"Division = $c";
}
}
$x=$_GET['a'];
