How can the use of 'empty' function in PHP improve code readability and efficiency?

Using the 'empty' function in PHP can improve code readability and efficiency by providing a concise way to check if a variable is empty (i.e., null, false, 0, or an empty string). This can help to streamline conditional statements and make the code easier to understand. 

// Example code snippet demonstrating the use of 'empty' function
$variable = ''; // Initialize a variable with an empty string

if (empty($variable)) {
    echo "Variable is empty";
} else {
    echo "Variable is not empty";
}
