In what scenarios would using a for loop be more appropriate than preg_match() for extracting values from a text in PHP?

Using a for loop would be more appropriate than preg_match() for extracting values from a text in scenarios where the text contains multiple occurrences of the value you want to extract and you need to process each occurrence individually. With preg_match(), you would only be able to extract the first occurrence of the value. 

$text = "The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog.";
$keyword = "fox";

$matches = [];
$words = explode(' ', $text);

foreach ($words as $word) {
    if ($word == $keyword) {
        $matches[] = $word;
    }
}

print_r($matches);
