Are there more elegant ways to check if a variable is set and equal to a specific value in PHP?

When checking if a variable is set and equal to a specific value in PHP, a more elegant way to do so is by using the `isset()` function along with a comparison operator. This ensures that the variable is set before checking its value, preventing any potential errors. Additionally, using a ternary operator can make the code more concise and readable. 

// Check if variable is set and equal to a specific value
$variable = "example";

// Using isset() and comparison operator
if (isset($variable) && $variable == "example") {
    echo "Variable is set and equal to 'example'";
} else {
    echo "Variable is not set or not equal to 'example'";
}

// Using ternary operator
$result = (isset($variable) && $variable == "example") ? "Variable is set and equal to 'example'" : "Variable is not set or not equal to 'example'";
echo $result;
