Are there any best practices for reading, incrementing, and writing values to a text file in PHP?

When reading, incrementing, and writing values to a text file in PHP, it's important to ensure proper file handling to prevent data corruption or loss. One best practice is to open the file in the appropriate mode (read, write, append) and close it after operations are complete. Additionally, using locking mechanisms can prevent conflicts when multiple processes are accessing the file simultaneously. 

// Read the current value from the text file
$file = 'counter.txt';
$current_value = file_get_contents($file);

// Increment the value
$new_value = $current_value + 1;

// Write the new value back to the text file
file_put_contents($file, $new_value);
