PHP if else statement

Description

We can providing an alternative choice with the else statement.

Syntax

The PHP if else statement has the following syntax.


if(condition_0){/*from  w w  w  .  ja  va 2  s . co m*/
...
}else{
...
}

or


if(condition_0){/*from   ww w .j  av a 2s  .  c  o  m*/
...
}elseif (condition_1){

}elseif (condition_2){

}else{
...
}

Note

else statement lets you run one block of code if an expression is true, and a different block of code if the expression is false.

Example 1


<?PHP//  w  w  w.  j  a  v a2 s.  com
$myValue = 23; 

if ( $myValue  >= 10 ) { 
 echo "greater than 10."; 
} else { 
 echo "Less than 10!"; 
}   
?>

The code above generates the following result.

Example 2

You can even combine the else statement with another if statement to make as many alternative choices as you like:


<?php/*from   ww  w.j a  va2 s .  c om*/
       
       $Age = 23; 
       if ($Age < 10) {
               print "You're under 10";
       } elseif ($Age < 20) {
               print "You're under 20";
       } elseif ($Age < 30) {
               print "You're under 30";
       } elseif ($Age < 40) {
               print "You're under 40";
       } else {
               print "You're over 40";
       }
?>

The code above generates the following result.
