When dealing with multiple values within a string in PHP, what are some best practices for extracting specific values?

When dealing with multiple values within a string in PHP, one best practice is to use functions like explode() or preg_match_all() to extract specific values based on a delimiter or pattern. These functions allow you to split the string into an array or extract matches based on a regular expression, making it easier to work with individual values. 

// Example using explode() to extract values based on a delimiter
$string = "apple,banana,orange";
$values = explode(",", $string);
print_r($values);

// Example using preg_match_all() to extract values based on a pattern
$string = "Today is 2022-01-01 and it's sunny";
preg_match_all("/\d{4}-\d{2}-\d{2}/", $string, $matches);
print_r($matches[0]);
