[RESOLVED] Simple RegEx

Hello,

Please let me know whats wrong with the following RegEx. I am trying to get 'tall' and 'taller' from the $str. But I am getting only 'tall'. Please help.

PHP Code:

---

<?php

$str = "Jack is a tall man but his brother is taller than him";
$pattern = "/tall(er)*/";
preg_match($pattern, $str, $matches);
print_r($matches);

?>

---

Thanks a lot in advance.

Thanks & Regards.

Code:

---

$pattern = "/tall(?:er)?/";

Hello,

Thnaks danasegarane for the reply. But this is not working in the PHP. There is no change in the result. I need help.

Thanks & Regards.

But when I am using online RegEx tool http://gskinner.com/RegExr/ and check the global option, it will mark both 'tall' and 'taller' with either of the syntaxes (danasegarane and myself, as explained above). Is there anything wrong with my configuration ? I become confused. Please help.

This worked for me

Code:

---

(tall|(?i)er)

Edit:
I don't have editor. So I tested here

Your main problem here is that you're using preg_match(), which stops searching after it finds its first match, as opposed to preg_match_all(), which matches everything it can find (a "global match" - which is why that regex tester was working for you). Your pattern is also a little off. Give this a shot:

Code:

---

<?php

$str = "Jack is a tall man but his brother is taller than him";
$pattern = "/tall(er)?/";
preg_match_all($pattern, $str, $matches);
print_r($matches);

?>
