10+ Basic PHP Programs

Hello everyone welcome again to my new article in which I am going to explain some basic PHP and its programs with their output.

With the help of these PHP programs, you can easily understand the working and syntax of this programming language.

PHP Programming

PHP (Hypertext Preprocessor) is a programming language that is used for web development. It is a server-side scripting language, which means that it is executed on the server and then results in HTML being sent to the client.

this language is often used to build dynamic web pages. Dynamic web pages are pages that display different content every time they are accessed.

How to create a PHP server in Linux

For creating its server in Linux you have to follow these steps: –

Navigate to the directory: – var/www/html/
Create a PHP file in the HTML directory
Write code in that file
Go to your browser
You can access the files in the HTML directory by: – localhost/filename.php

Create a file by following these steps if you are not an administrator: –

Open the terminal and navigate to /home/cipherss/public_html/html/ directory
And then run this command: – sudo touch filename.php

Basic PHP Programs

Write a program to print “HELLO WORLD”

<?php
$a = "HELLO WORLD";
echo $a;
?>


//output in browser

Write a program to check leap year

<?ph
$year = 2020;  
 
if($year % 4 == 0)
{
    echo $year .""."is a Leap Year.";    
}
else  
{  
    echo "$year is not a Leap Year.";    
}
?>




//output in browser

2020 is a Leap Year.

Write a program to print a table of 7

<?php    


$a = 7;  
echo "Table of 7 is: <br>";
echo "<br>";
for($i=1; $i<=10; $i++)   
{
    $b = $i*$a;
    echo "$a * $i = $b";   
    echo '<br>';	 
}  



?>

//output in browser

7 * 1 = 7
7 * 2 = 14
7 * 3 = 21
7 * 4 = 28
7 * 5 = 35
7 * 6 = 42
7 * 7 = 49
7 * 8 = 56
7 * 9 = 63
7 * 10 = 70

Write a program to print the Fibonacci series of number

<?php  
$num = 0;  
$n1 = 0;  
$n2 = 1;  
echo "Fibonacci series for first 8 numbers: -";  
echo "<br>";  
echo $n1.' '.$n2.' ';  
while ($num < 10 )  
{  
    $n3 = $n2 + $n1;  
    echo $n3.' ';  
    $n1 = $n2;  
    $n2 = $n3;  
    $num = $num + 1;  
}
?>



//output in browser



Fibonacci series for first 8 numbers: -
0 1 1 2 3 5 8 13 21 34 55 89

Write a program to print a Factorial of 5

<?ph
$num = 5;  
$fact = 1;
  
for ($x=$num; $x>=1; $x--)   
{  
    $fact = $fact * $x;  
}  
echo "Factorial of $num is: -" .$fact;  
?>



//output in browser


Factorial of 5 is: - 120

Write a program to check Armstrong’s number

<?php  
 
$num = 407;  
$sum = 0;  
$i = $num;
 
while($i!=0)  
{  
    $x=$i%10;  
    $sum=$sum+$x*$x*$x;  
    $i=$i/10;  
}
 
if($num==$sum)  
{  
    echo $num." is an Armstrong Number.";  
}  
 
else  
{  
    echo $n." is not an Armstrong Number.";  
}  
?>




 
 
//output in browser


407 is an Armstrong Number.

Write a program to check the Palindrome number

<?php  
 
$num = 12321;  
$i = 0;
$n = $num;
 
while(floor($num))
{  
    $mod = $num%10;
    $i = $i * 10 + $mod;  
    $num = $num/10;
}  
 
if($n==$x)
{  
    echo $n." is a Palindrome number.";  
}
 
else
{  
    echo $n." is not a Palindrome number.";  
}  
?>






//output in browser


12321 is not a Palindrome number.













.

Write a program to print the reverse of the number

<?php  
$num = 12345;  
$rev = 0;  
while ($num > 1)  
{  
    $rem = $num % 10;  
    $rev = ($rev * 10) + $rem;  
    $num = ($num / 10);   
}  
echo "Reverse number of 12345 is " .$rev;  
?>



//output in browser


Reverse number of 12345 is 54321

Write a program for swapping 2 numbers

Using the third variable

<?php  
$a = 40;  
$b = 50;
  
$c = $a;  
$a = $b;  
$b = $c;
  
echo "After swapping: -<br>";  
echo "a =".$a."  b=".$b;  
?>



//output in browser


After swapping: -
a = 50 b = 40

Without using a third variable

<?php  
$a = 40;  
$b = 50;  
  
$a = $a + $b;  
$b = $a - $b;  
$a = $a - $b;  

echo "After swapping: <br>";
echo "Value of a: - " .$a ."</br>";  
echo "Value of b: - " .$b ."</br>";  
?>



//output in browser


After swapping: -
Value of a: - 50
Value of b: - 40

Write a program to find the area of given 2D shapes

Area of circle

<?php  
$r = 2;  
$area = 3.14 * $r * $r;
  
echo "Area of circle is: -" .$area;  
?>


//output in browser

Area of circle is: - 12.56

Area of rectangle

<?php  
$l = 10;  
$b = 20;  
$area = $l * $b;

echo "Area of rectange is: - " .$area;
?>


//output in browser

Area of rectangle is: - 200

Area of triangle

<?php  
$l = 10;  
$b = 20;  
$area = 1/2 * $l * $b;

echo "Area of triangle is: - ".$area; 
?>



//output in browser

Area of triangle is: - 100

Area of square

<?php  
$a = 10;
$area = $a * $a;  

echo "Area of square is: - ".$area;
?>



//output in browser


Area of square is: - 100
