How can error reporting help in troubleshooting array access issues in PHP?

Error reporting can help in troubleshooting array access issues in PHP by providing detailed information about the error, such as the line number and type of error. This can help identify where the issue is occurring in the code and what specific problem is causing it. By enabling error reporting and carefully reading the error messages, developers can quickly pinpoint and resolve array access issues. 

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

// Example array access issue
$colors = array('red', 'green', 'blue');
echo $colors[3]; // Trying to access an index that doesn't exist

// Fix the array access issue by checking if the index exists before accessing it
if(isset($colors[3])) {
    echo $colors[3];
} else {
    echo "Index does not exist in the array.";
}
?>
