2. Syntax for PHP Ternary Operator
3. Note for PHP Ternary Operator

Description

The ternary operator is a shorthand for if statements.

Syntax

PHP ternary operator has following syntax.

Note

The ternary operator takes three operands:

• a condition (expression1),
• a result(expression2) for true, and
• a result(expression3) for false.

The preceding code reads as follows:

If expression1 evaluates to  true, 
  the overall expression equals  expression2 ;  
otherwise, 
  the overall expression equals  expression3 .  

Example

<?PHP/*from   ja v  a 2  s  .  c om*/
$age = 10;
$agestr = ($age < 16) ? 'child' : 'adult'; 
print $agestr;
?>

The code above generates the following result.

That ternary statement can be expressed in a normal if statement like this:

<?PHP/*from   ja  v  a  2 s  .c o  m*/
      $age = 10;
      if ($age < 16) { 
             $agestr = 'child'; 
      } else { 
             $agestr = 'adult'; 
      } 
?>
