Are there any best practices or tips for efficiently extracting text using PHP?

When extracting text using PHP, it is important to use the appropriate functions and methods efficiently to avoid unnecessary processing and improve performance. One best practice is to use built-in PHP functions like `file_get_contents()` or `DOMDocument` to extract text from files or HTML documents. Additionally, regular expressions can be used for more complex text extraction tasks. 

// Example of extracting text from a file using file_get_contents()
$filename = 'example.txt';
$text = file_get_contents($filename);
echo $text;
