Question

Hello I've studying regex and I want know why:

This code:

<?PHP
$str = '<TD class=""><option value="123">abc</option>
</TD>
        <TD class=""><option value="123">abcwda</option>
        </TD>';

preg_match_all('#<TD([\S\s]+)</TD>#s', $str, $tabela);
?>

Return:

Array
(
    [0] =>  class=""><option value="123">abc</option>
</TD>
        <TD class=""><option value="123">abcwda</option>

)

And why does it not return:

Array
(
    [0] =>  class=""><option value="123">abc</option>
    [1] =>  class=""><option value="123">abcwda</option>

)

?

You should also learn that using `REGEX` is not a good approach for parsing `HTML` instead use `DOMDocument` — Sahil Gulati, Jun 01 '17 at 12:07
...that does not help you, it actually works "against" you. Don't use caps, ever. bit of a tip for you ;-) if your "code" contains caps, then that's a different animal. — Funk Forty Niner, Jun 01 '17 at 12:13
Why do you think caps makes it easier to read? If that was the case then all books/webpages/ etc. would be in caps — Andreas, Jun 01 '17 at 12:13
Is the html tags important to you? If not, use a different too. Regex and html is not a good combo. — Andreas, Jun 01 '17 at 12:15

Because of greedy +. Use its lazy counterpart (+?):

preg_match_all('#<TD(.+?)</TD>#s', $str, $tabela);

Please also note that since you're using the /s modifier, . will match newline characters so you don't need the [\S\s] construct.
