php_programs

1.simple and 1st program of php:-

<?php
echo "this is my first program.;"
>

o/p= this is my first program.


here  "echo" keyword is used for print the data. we start php with "<php " and end with ">"

2.program Switch case in php

<?php

$day="sun";

switch ($day)

{

case "sun":

 echo "today is Sunday";

 break;

case "Monday":

echo "today is Monday";

break;

case "Tuesday":

echo "today is Tuesday";

break;

case "Wednesday":

echo "today is Wednesday";

break;

default:

echo "today is ?";

}

?>




3.If-else condition program in php
<?php
$a=10;
if($a=10)
{
echo "this is true";
}
else
{
echo"this is false";
}
?>

o/p= this is true


we take a variable  "a" and it's value is 10.
in php we define variable with '$'
after this we define apply if condition . if a = 10 then it print "this is true"
otherwise it print "this is false".
