How can PHP beginners ensure they are properly handling file operations to avoid data loss or corruption?

PHP beginners can ensure they are properly handling file operations by using error handling techniques, such as checking for file existence before reading or writing to it, using appropriate file modes for opening files, and closing files after use. They should also consider implementing backup mechanisms or version control to prevent data loss or corruption. 

// Example of properly handling file operations in PHP

$filename = 'example.txt';

// Check if the file exists before reading from it
if (file_exists($filename)) {
    $file = fopen($filename, 'r');
    
    // Read from the file
    
    fclose($file); // Close the file after use
} else {
    echo 'File does not exist.';
}

// Example of writing to a file
$file = fopen($filename, 'w');
fwrite($file, 'Hello, World!');
fclose($file);
