How can PHP developers optimize the use of ternary operators for conditional statements?

To optimize the use of ternary operators for conditional statements in PHP, developers should ensure that the conditions are simple and easy to understand. Avoid nesting ternary operators excessively as it can make the code harder to read and maintain. Use ternary operators only for simple conditional assignments where the logic is straightforward. 

// Example of optimizing the use of ternary operators for conditional statements
$age = 25;

// Bad practice - nested ternary operators
$result = ($age >= 18) ? (($age >= 21) ? 'Adult' : 'Young Adult') : 'Teenager';

// Good practice - simple ternary operator
$result = ($age >= 21) ? 'Adult' : ($age >= 18 ? 'Young Adult' : 'Teenager');

echo $result;
