In PHP, what are some alternative methods to efficiently clean up text, such as using str_replace and preg_replace functions, and what considerations should be taken into account when choosing between them?

When cleaning up text in PHP, using functions like str_replace and preg_replace can be efficient methods. Str_replace is useful for simple text replacements, while preg_replace is more powerful and allows for pattern matching using regular expressions. When choosing between them, consider the complexity of the text cleaning task and whether regular expressions are necessary for the job.

// Example of using str_replace to clean up text
$text = "Hello, this is a sample text.";
$cleaned_text = str_replace('sample', 'cleaned', $text);
echo $cleaned_text;

// Example of using preg_replace to clean up text with a regular expression
$text = "123-456-7890";
$cleaned_text = preg_replace('/[^0-9]/', '', $text);
echo $cleaned_text;
