How can error reporting and display be optimized in PHP scripts to identify and address issues like variable assignment errors?

To optimize error reporting and display in PHP scripts to identify and address issues like variable assignment errors, you can enable error reporting, use proper error handling techniques, and utilize functions like isset() to check if a variable is set before using it to prevent assignment errors.

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Check if a variable is set before using it
if(isset($variable)){
    // Use the variable here
} else {
    // Handle the case where the variable is not set
}
