How can different words be extracted from a text in PHP?

To extract different words from a text in PHP, you can use the `explode()` function to split the text into an array of words based on a specified delimiter, such as a space or punctuation mark. You can then loop through the array to process and extract individual words as needed.

$text = "This is a sample text to extract words from.";
$words = explode(" ", $text);

foreach($words as $word){
    echo $word . "<br>";
}
