PHP Ternary Operator: A Simple Guide with Examples

Introduction

The PHP ternary operator is a simple and concise way to write conditional statements. It can be used as a shorter alternative to the if...else statement when you need to check a condition and return one of two values. In this article, we will explain the PHP ternary operator with simple examples and show how it can be used instead of traditional if...else and nested conditional statements.

Prerequisites

Before working with the examples in this article, you should have:

• Basic knowledge of PHP.
• Basic understanding of variables and conditional statements.
• A PHP development environment such as XAMPP, WAMP, LAMP, or a PHP-enabled web server.
• Basic knowledge of using if, else, and elseif statements.

Implementation

In this post, we will explain the PHP ternary operator.

Example:

In this example, we are using an if-else condition

<?php
$a=16;
if($a>18)
{
  echo "Eligible For Vote";
}
else
{
  echo "Not Eligible For Vote";
}
?>

In the above example $a value is greater than 18 eligible vote, Otherwise not eligible for vote. In this example, we are using an if condition. One more way to achieve result using php ternary operator.

Ternary Example

echo($a>18 ? 'Eligible For Vote':'Not Eligible For Vote');

Example 2:

In this example, we are using a nested if condition

<?php
$status=2;
if($status==1)
{
  echo "Stop";
}
elseif ($status==2) 
{
  echo "Ready";
}
else if($status==3)
{
  echo "Go";
}
else
{
  echo "Something went wrong";
}
?>

In the above example $status value is 1, then “Stop”; if the $status value is 2, then “Ready”, if the $status value is 3, then “Go”. One more way to achieve the result is using the PHP ternary operator.

<?php
echo($status==1 ? 'Stop':($status==2 ? 'Ready' :($status==3 ? 'Go':'Something went wrong')));
?>

Conclusion

The PHP ternary operator provides a convenient way to simplify conditional statements and make code more concise. It is particularly useful when you need to choose between two values based on a condition. For multiple conditions, nested ternary operators can also be used, although traditional if...elseif...else statements may be easier to read and maintain when the logic becomes complex.
