How can PHP error reporting settings be optimized to provide more detailed information when encountering issues with file writing functions like fwrite?

When encountering issues with file writing functions like fwrite in PHP, it is important to optimize the error reporting settings to provide more detailed information. This can be done by setting the error_reporting level to E_ALL and enabling display_errors in the php.ini file. Additionally, using the error_log function to log errors to a file can also help in debugging file writing issues. 

// Set error reporting level to display all errors
error_reporting(E_ALL);

// Enable displaying errors
ini_set('display_errors', 1);

// Log errors to a file
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');

// Example code using fwrite
$file = 'example.txt';
$data = 'Hello, World!';

$handle = fopen($file, 'w');
if ($handle === false) {
    error_log('Error opening file for writing: ' . $file);
} else {
    if (fwrite($handle, $data) === false) {
        error_log('Error writing data to file: ' . $file);
    } else {
        echo 'Data written to file successfully!';
    }
    fclose($handle);
}
