Conditional Statements

Very often when you write code, you want to perform different actions for
different decisions.

You can use conditional statements in your code to do this.

if...else statement - use this statement if you want to execute
a set of code when a condition is true and another if the condition is not
true

elseif statement - is used with the if...else statement to
execute a set of code if one of several condition are true

The If...Else Statement

If you want to execute some code if a condition is true and another code if a
condition is false, use the if....else statement.

Syntax

if (condition)
  code to be executed if condition is true;
else

  code to be executed if condition is false;

Example

The following example will output "Have a nice weekend!" if the current day
is Friday, otherwise it will output "Have a nice day!":

<html>
<body>

<?php
$d=date("D");
if ($d=="Fri")
  echo "Have a nice weekend!"; 
else
  echo "Have a nice day!"; 
?>

</body>
</html>
