What changes in PHP versions could affect the functionality of code using if/else statements?

Changes in PHP versions could affect the functionality of code using if/else statements if there are changes in the syntax or behavior of the language. To ensure that your code remains compatible across different PHP versions, it's important to stay updated on any changes and make necessary adjustments to your code. 

// Example of using the ternary operator as a more concise alternative to if/else statements
$condition = true;

// Using if/else statement
if ($condition) {
    $result = 'Condition is true';
} else {
    $result = 'Condition is false';
}

echo $result;

// Using ternary operator
$result = $condition ? 'Condition is true' : 'Condition is false';

echo $result;
