Answer 1

1) preg_match_all("/.*?\,/",    $variable(где лежит нужный текст),    $variable(куда будет вложен текст)  );
2) preg_match_all("/\d\d\d\d\-\d\d\-\d\d/",    $variable(где лежит нужный текст),    $variable(куда будет вложен текст)  );

regular expressions are the most primitive, but
str_replace is suitable for your options - this is for replacing with a regular
expression date_parse_from_format - getting information about a date in a specific format
