How can the issue of undefined variables in PHP code be resolved instead of suppressing error messages?

When dealing with undefined variables in PHP code, it is important to initialize variables before using them to avoid errors. One way to resolve this issue is to use the isset() function to check if a variable is set before using it in your code. This helps prevent errors and ensures that your code runs smoothly without suppressing error messages. 

// Initialize variable to avoid undefined variable error
$variable = '';

// Check if variable is set before using it
if(isset($variable)){
    // Use the variable safely here
    echo $variable;
} else {
    // Handle the case where the variable is not set
    echo "Variable is not set";
}
