Simple PHP Program for Beginners

1. Printing patterns Using For Loop
<?php
$n=5;
for ($i=1; $i<=$n; $i++)
{
for ($j=0; $j<=$i; $j++)
{
echo "* ";
}
echo "<br>";
}
?>
Output:
* *
* * *
* * * *
* * * * *
* * * * * *

2. Simple Program Using Function
<?php
function salary($name, $salary)
{
echo "$name starting salary is $salary <br>";
}
salary("manisha",50000);
salary("manju",35000);
salary("nive",80000);
?>
Output:
manisha starting salary is 50000
manju starting salary is 35000
nive starting salary is 80000

3. Recursive Function To Print Fibbonacci Series
<?php
$a=-1;
$b=1;
$c=0;
function fib($n)
{
global $a, $b, $c;
if($n>0)
{
$c= $a+ $b;
$a= $b;
$b= $c;
echo " $c <br>";
fib($n-1);
}
}
echo "Printing Frist 10 Fibonacci series<br>";
fib(10);
?>
Output:
Printing Frist 10 Fibonacci series
0
1
1
2
3
5
8
13
21
34

4. Simple Program Using Default Function
<?php
functiondefault_fun($name,$dept="MCA")

switch($n)
{
case 0:
echo " $year is a leap year<br>";
break;
default:
echo " $year is not a leap year <br>";

2000 is a leap year
3000 is not a leap year

6. Multiplication Table
<?php
$n=5;
for($i=1;$i<=10;$i++)
{
$sum=$i*$n;
echo "$i * $n = $sum";
echo "<br>";
}
?>
Output:
1 * 5 = 5
2 * 5 = 10
3 * 5 = 15
4 * 5 = 20
5 * 5 = 25
6 * 5 = 30
7 * 5 = 35
8 * 5 = 40
9 * 5 = 45
10 * 5 = 50

7. Sum Of Digits
<?php
$num=1234;
$sum=0;
if($num)
{
echo "The number is $num<br>";
while($num!=0)
{
$r=$num%10;
$sum=$sum+$r;
$num=$num/10;
}
echo " Sum is $sum";
}
?>
Output:
The number is 1234
Sum is 10
