php preg_replace content type

Question

How can I check if the content of preg_replace function is numeric/alphanumeric or not?

e.g.

if numeric :

$link= preg_replace("'\< (.*)\>'Ui","< <a href=\"x.php?id=\\1\">\\1</a>>",$link);

else

$link= preg_replace("'\< (.*)\>'Ui","< <a href=\"x.php?word=\\1\">\\1</a>>",$link);

Have a look on ctype_alnum() function

bool ctype_alnum ( string $text )
Checks if all of the characters in the provided string, text, are alphanumeric. In the standard C locale letters are just [A-Za-z].
