PHP IF...ELSE Statement

• if ... else statement -  if...else statement is used when a different sequence of instructions is to be executed depending on the logical value ( True / False ) of the condition evaluated.

The Syntax is as follows :

     

      if(condition)

           statement - 1 ;

     else

          statement - 2 ;

     statement - 3;

OR

     if(condition)

       {

            Statements - 1

       }

    else

     {

           Statement - 2

     }

 Statement - 3

if the condition is true, then the sequence of statement (statement - 1) execute; other wise the statement - 2 following the else part of if-else statement will get executed. In both the cases,the control is then transferred to statement - 3 to follow sequential execution of program.

Example : 

    To print whether the given number is even or odd.

<?php

       $x = 10;

       if($x % 2 == 0)

        {

           echo "<br/> The Given number is even";

        }

    else

       {

          echo "<br/>The Given number is odd";

      } 

?>
