What are some best practices for separating strings in PHP, especially when dealing with comments in a text file?

When separating strings in PHP, especially when dealing with comments in a text file, one best practice is to use regular expressions to identify and extract the desired strings. Regular expressions can help you define patterns for identifying comments within the text file and then extract them accordingly. Another best practice is to use PHP's built-in functions like preg_match_all() to efficiently extract multiple occurrences of comments from the text file. 

<?php

// Sample text file content
$text = "This is a sample text file.
// This is a comment
Another line of text.
/* This is a multi-line comment
that spans multiple lines */";

// Use regular expressions to extract single-line comments
preg_match_all('/\/\/(.*)/', $text, $singleLineComments);

// Use regular expressions to extract multi-line comments
preg_match_all('/\/\*(.*?)\*\//s', $text, $multiLineComments);

// Output extracted comments
echo "Single-line comments: \n";
print_r($singleLineComments[1]);

echo "\nMulti-line comments: \n";
print_r($multiLineComments[1]);
?>
