How can error reporting in PHP be utilized to identify and address issues with variable declaration and display?

When dealing with variable declaration and display issues in PHP, error reporting can be utilized to identify and address these problems. By enabling error reporting, PHP will display any notices or warnings related to variable declaration and display, making it easier to pinpoint the source of the issue. This can help in fixing problems such as using undefined variables or trying to display variables that have not been properly initialized. 

<?php
// Enable error reporting to display notices and warnings
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Example of variable declaration and display issue
$variable1 = "Hello";
echo $variable2; // $variable2 is not defined

// Corrected code
$variable2 = "World";
echo $variable2;
?>
