Are there any best practices for handling tabs and spaces in text files when using PHP?

When working with text files in PHP, it's important to be consistent with the use of tabs and spaces to avoid formatting issues. One common best practice is to choose either tabs or spaces for indentation and stick with it throughout the file. If you need to convert tabs to spaces or vice versa, you can use PHP functions like `str_replace()` to achieve this.

// Replace tabs with spaces
$fileContents = file_get_contents('example.txt');
$fileContents = str_replace("\t", "    ", $fileContents);
file_put_contents('example.txt', $fileContents);
