How can the EVA principle be applied to improve the efficiency of file handling in PHP?

Issue: The EVA principle (Eliminate, Visualize, Automate) can be applied to improve the efficiency of file handling in PHP by eliminating any unnecessary file operations, visualizing the file structure to better understand the flow of data, and automating repetitive tasks to reduce manual effort. PHP Code Snippet: 

// Eliminate: Check if file exists before performing any file operations
if (file_exists('example.txt')) {
    // Visualize: Get the contents of the file and display it
    $file_contents = file_get_contents('example.txt');
    echo $file_contents;
    
    // Automate: Write data to a new file automatically
    $new_file_contents = 'This is new content';
    file_put_contents('new_file.txt', $new_file_contents);
}
