What best practices should be followed when handling empty error checking in PHP?

When handling empty error checking in PHP, it is important to check if a variable is empty before attempting to access or manipulate it to avoid potential errors or warnings. One common practice is to use the `empty()` function to check if a variable is empty before proceeding with any operations. Additionally, using conditional statements like `if` or `ternary operators` can help handle empty values gracefully and prevent unexpected behavior in your code. 

// Example of handling empty error checking in PHP

// Check if a variable is empty before accessing it
$variable = ''; // Empty variable
if (!empty($variable)) {
    // Proceed with operations if variable is not empty
    echo $variable;
} else {
    // Handle empty variable case
    echo 'Variable is empty';
}

// Using ternary operator for concise empty checking
$variable = ''; // Empty variable
$output = !empty($variable) ? $variable : 'Variable is empty';
echo $output;
