In what scenarios is it recommended to use preg_match_all over other string manipulation functions in PHP?
When you need to extract multiple occurrences of a pattern from a string, it is recommended to use preg_match_all over other string manipulation functions in PHP. This function allows you to specify a regular expression pattern to match against the string and retrieve all matches in an array, making it easier to work with multiple occurrences of a pattern.
$string = "The quick brown fox jumps over the lazy dog";
$pattern = '/\b\w{4}\b/'; // Match 4-letter words
preg_match_all($pattern, $string, $matches);
print_r($matches[0]); // Output: Array ( [0] => quick [1] => brown [2] => jumps over lazy )
